ABSTRACT
The Island Mountain copper mine is in the southwestern corner of Trinity County,
in the Horseshoe district about 90 miles north of Ukiah and 30 miles east of
Garberville.
The deposit is a massive sulfide body consisting largely of pyrite, chalcopyrite,
and pyrrhotite, with minor amounts of arsenopyrite, galena and sphalerite, and
recoverable amounts of gold and silver. During the period of production from 1915
to 1930, 9,000,000 pounds of copper, 144,000 ounces of silver, and 8.600 ounces of
gold were recovered.
The rocks in the mine area are largely graywacke with isolated bodies of shale,
chert, and glaucophane schist, all belonging to the Franciscan group of Upper
Jurassic (?) age. The sedimentary rocks strike N. 30° W. with steep northeasterly
dips.
The sulfide deposit at Island Mountain is of the pyritic replacement type, belong-
ing to the mesothermal zone of deposition. Metallic minerals present are magnetite,
pyrite, pyrrhotite, chalcopyrite, arsenopyrite, sphalerite, bornite, and galena ; an
assemblage characteristic of high temperature conditions of formation. Gold and
Nos. land 2] island mountain mine, trinity county 11
silver present in small quantities are probably carried by the pyrite and chalcopyrite
in solid solution or as mechanical admixtures. Secondary enrichment with the for-
mation of secondary copper and iron minerals has occurred to a limited extent along
the upper contact of the ore body.
The ore body occurs as a lenticular mass of sulfide minerals along a shear zone
in a slightly metamorphosed shale. Intensely sheared zones in the shale have been
the most favorable structural control in ore deposition. The rock is sheared appar-
ently in several directions but the average is northwest and roughly parallel to the
strike of the bedding of the sedimentary rocks in the immediate mine area.
Post-mineral parallel or nearly parallel faults having a strike parallel to the
strike of the bedding in the sedimentary rocks and a nearly vertical dip, are present
at Island Mountain.
INTRODUCTION
Recent national demands for increased production of copper, iron
and sulfur have prompted extensive searches for sources of these stra-
tegic minerals. In addition to the search for new deposits, an investiga-
tion of deposits of low-grade ore which have been mined in the past is
being carried on.
The massive sulfide deposit at Island Mountain, Trinity County,
California, is owned by E. R. Leach of Oakland, California, and asso-
ciates, and is one of the largest sulfide ore bodies known in rocks of
the Franciscan group. Originally the known ore body consisted of
approximately 280,000 tons of sulfide ore containing recoverable
amounts of copper, silver, and gold. From 1915 to 1930, 132,000 tons
of ore were mined producing 9,000,000 pounds of copper, 144,000 ounces
of silver, and 8,600 ounces of gold. The remaining estimated 158,000
tons of ore in the deposit has not been worked since the mine closed
in 1930.
The mine property is located in sections 9, 10, and 15, T. 5 S., R.
6 E., Humboldt Meridian, and consists of 266 acres of land as follows:
four mining claims of 57 acres held under government minerals patent ;
106 acres held under agriculture patents; and 103 acres for which the
state has issued its certificate of purchase.
The field examination of the Island Mountain area that furnished
the basis for this report was made by the writer assisted by J. Grant
Goodwin during the last two weeks in October, 1952. During this time
the immediate mine area was mapped in detail with a plane table and
data for a geologic map was obtained. Further field work was done by
the writer in July 1953.
The only U. S. Geological Survey topographic maps available which
include the area studied are the Hoaglin quadrangle map with a scale
of 1 : 125,000 and a 100-foot contour interval, and the Kettenpom quad-
rangle preliminary blueline map with a scale of 1 : 48,000 and a 50-foot
contour interval. A series of U. S. Forest Service aerial photographs is
available and was used as a base map for a general geologic reconnais-
sance of the area.
The author wishes to express his appreciation to Mr. E. R. Leach for
making available old reports, photographs, production records, and
underground maps of the Island Mountain mine and to Mr. George
Norris who worked in the mine and was able to supply the writer with
much first hand information. The writer is also indebted to Gordon
D. Bath of the Geological Survey for providing the results of a pre-
liminary magnetometer survey of the mine area.

Little information has previously been published regarding the
geology of this region. The only information available is found in re-
ports by Anbury (1902, pp. 124-126, 1908, pp. 148-150), Brown (1913-
1914, p. 881), and Miller (1890, p. 716) on the Island Mountain Con-
solidated copper mine. Several private mine reports 1 are believed to
exist but the writer was able to refer to only one of these 2 and a pre-
liminary report by E. R. Leach in 1911 or 1912. 3
Geography. Island Mountain is a Northwestern Pacific railroad sta-
tion which lies at an elevation of 550 feet on the west bank of the Eel
River in the southwestern corner of Trinity County. It is in Township 5
South, Range 6 East, Humboldt Meridian, about 90 miles north of
Ukiah and 30 miles east of Garberville. U.S. Highway 101 passes within
30 miles of Island Mountain ; the remaining 30 miles is traversed by
an improved dirt road and 5 miles of unimproved dirt road. During
extremely wet winters the last 5 miles of the road is ordinarily im-
passable for several months. The Northwestern Pacific railroad line
between San Rafael and Eureka passes within 400 yards of the mine.
When the mine was in operation, an ore bin was located on a railroad
siding a few hundred yards north of the present Island Mountain
station.
The mine area lies in the Northern Coast Ranges geomorphic pro-
vince (Jenkins, 1943, pp. 82-89), a region characterized by northwest-
trending ridges and valleys. The area is fairly rugged, having steep
hills, narrow deep canyons, and numerous jagged pinnacles of green-
stone. Most of the ridges are two to three thousand feet in elevation ;
the ridge to the east of the settlement is nearly four thousand feet.
Landslides are very common, especially in the mine area, where a huge
slide occurred in 1937. Numerous permanent springs provide an ad-
equate water supply.
Winter rainfall is generally heavy and floods are not uncommon.
Occasionally snow falls but usually only in small amounts.
REGIONAL GEOLOGY
All of the rocks in the vicinity of Island Mountain, with the excep-
tion of a small body of hornblende andesite and the landslide material
and alluvium, are tentatively assigned to the Franciscan group of
LTpper Jurrasic (?) age. The map units shown on the accompanying
map are : graywacke ; black shale ; red, green, and gray chert ; green-
stone ; diabase ; andesite ; glaucophane schist ; Tertiary hornblende
andesite ; landslide material ; and alluvium.
Rock Units
Franciscan Group
Graywacke. The most widespread rock type at Island Mountain is
well bedded graywacke. The typical graywacke is medium-grained and
1 According- to Mr. E. R. Leach there have been two unpublished reports on the Island
Mountain mine. The first report was written by W. B. Devereau prior to 1905 ; the
second was written by A. C. Lawson in 1918.

is composed mostly of sub-angular grains of quartz with subordinate
plagioclase in the oligoclase-andesine range, and sufficient black shale
fragments to give the rock a grayish green color. The percentage of
shale fragments in the rock varies from less than 5 percent to over
25 percent.
A zone of graywacke exposed along Pine Creek below the bridge
consists of alternate layers of fine-grained graywacke and graywacke
containing rounded, roughly aligned pebbles of black shale. The largest
pebbles are a centimeter or more in diameter. The pebbles average
about 0.5 cm. in diameter.
Many of the prominent ridges are composed of graywacke, as it is
very compact and resistant to weathering. Most of the landslides have
occurred at or near the contact between graywacke and lenticular
bodies of black shale incorporated in shear zones.
Black Shale. The black shale bodies that are enclosed by the gray-
wacke are narrow and lenticular, having an average width of about
100 feet. Most of the shale is thoroughly fractured and in some local-
ities has been slightly metamorphosed to a pencil shale. Locally it is
almost a slate. The shale is composed largely of quartz and feldspar
and enough carbonaceous material to give it a black color.
In the landslide area near the mine, particularly at the upper end
of the landslide, the shale has been silicified and re-cemented to form
massive boulders.
Chert. Also within the graywacke are lenses of chert which are
aligned approximately parallel to the general strike of the graywacke
(N30°W). Most of the chert is red or brown in color; locally the chert
is gray or green in color.
Massive red and brown chert comprises the western half of a large
bluff overlooking the ore deposit. It is in contact with glaucophane
schist on the east side and in fault contact with graywacke on the west
side. The upper and lower contacts are concealed by landslide mate-
rial. The chert is thoroughly fractured and partly recrystallized. Vein-
lets of calcite, which are abundant in the chert, fill the interstices and
cement the fractured rock. The red and brown color is caused by a
hematite-limonite stain. Radiolaria replaced by silica are found only
in the red and brown chert.
A lens of bedded gray and green chert forms a small ridge trending
northwest along the eastern edge of the landslide in the immediate
mine area. The gray and green chert contains no iron minerals but
does contain chlorite and aegerine. The bedding in the chert strikes to
the northeast and dips to the northwest.
A lens of thoroughly fractured and folded, thin-bedded, gray-green,
banded chert is near the west end of the railroad quarry about 200
yards south of Island Mountain settlement. The chert is separated from
the graywacke by a 5-foot zone of fractured black slaty schist and
gouge. This zone appears to be the southeast extension of the fault that
passes through the mine area.
Greenstone. Many sharp, jagged pinnacles of greenstone rise above
the tops of the ridges in the area. A large mass of greenstone, just
south of the settlement of Island Mountain is being quarried by the

Northwestern Pacific for use as road metal. The greenstone at this local-
ity is a very compact, unweathered rock composed of feldspar and
chlorite, containing many veins and veinlets of calcite and quartz, and
in some places a considerable amount of pyrite.
The other greenstone bodies are composed of rock very similar in
appearance to that exposed in the railroad quarry. A small mass of
greenstone and gray chert is found along the railroad track near the
southeastern edge of the mapped area. This body of rock does not
appear to be in place — possibly it slid down from the large pinnacle
to the east.

Diabase. A small body of diabase is exposed about a third of a mile
southeast of the north end of the railroad tunnel. The diabase forms
a low, flat bluff about 30 feet high, which can be seen from Copper
Creek. The discordance between the steeply dipping graywacke and
the nearly horizontal diabase suggests that the diabase body is a dike.
The diabase is a fairly compact rock containing lath-shaped crystals
of andesine in a groundmass of an altered pyroxene, probably augite,
and some scattered pyrite and magnetite. Numerous veins of white
secondary quartz occur in the diabase near the bottom of the bluff.
A gold prospect was reported 4 to have been located here and to have
yielded several tons of gold-bearing quartz, but the writer noted no
evidence of mineralization in the quartz veins.
Andesite. Three small but prominent outcrops of andesite on the
slope above the mine and a larger mass of andesite exposed several
hundred yards farther west probably indicate a body intrusive into
the graywacke.
The andesite is composed of altered plagioclase, unidentified ferro-
magnesian minerals, and a small proportion of magnetite and pyrite.
The rock has been badly altered to chlorite, epidote, and veins of cal-
cite. This rock, for reasons to be discussed in a following section, is
believed to be older than the porphyritic hornblende andesite that
occurs on the slope above the railroad tunnel. A late Mesozoic age,
possibly late Jurassic, has been given to the altered andesite.
Glaucophane Schist. Several isolated masses of glaucophane schist
form prominent outcrops in the Island Mountain area. A large body of
glaucophane schist forms a bluff overlooking the mine. The schist is in
sharp contact on the west with brown, iron-stained chert that makes
up the western two-thirds of the bluff. The eastern contact of the schist
and the black shale is gradational. The glaucophane schist is progres-
sively richer in chlorite, muscovite, and actinolite toward its contact
with the shale. Secondary quartz both as veins and as crystals lining
small cavities is in the zone nearest the shale. Accessory minerals in
the schist include muscovite, chlorite, actinolite, epidote, calcite, quartz,
pyrite, and lawsonite (?). Whether or not the glaucophane schist is
in place could not be determined from available evidence.
A large body composed of chlorite schist grading into glaucophane
schist is exposed on the north slope of the mountain on which the mine
is located. This body contains zones of pyrite, largely in the chlorite
schist and red garnet crystals, chiefly in the glaucophane schist. Other
masses of glaucophane schist, such as the one that forms the large knob
west of the Island Mountain settlement, contain various proportions
of chlorite. Calcite, epidote, actinolite, and pyrite also are locally
present in the schist.
Porphyritic Hornblende Andesite
A small flat-lying body of porphyritic andesite crops out near the
top of the mountain through which the railroad passes. The andesite
is composed of plagioclase in the andesine-oligoclase range, dark green
to brown euhedral crystals of hornblende, and a small amount of biotite,
George Norris, personal communication, 1952.
16 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
pyrite, and magnetite. The andesite at this locality differs greatly in
appearance from the andesite found at other localities. The most notable
difference, in addition to its lack of alteration, is its different struc-
tural relationship. The andesite found at the other localities, in addition
to being badly altered and non-porphyritic, is probably intrusive into
the graywacke. The porphyritic hornblende andesite probably origi-
nated as a surface or near surface flow. For these reasons, a Tertiary
age has been assigned to this andesite.
Landslide Material
Although many landslides are to be seen in this region, most of them
are restricted to zones of black shale in the graywacke. These areas are
almost all marked by water seeps which flow throughout the year.
Landslide debris consisting of soil, talus, and some mine dump ma-
terial covers the ore deposit and most of the bedrock in the area imme-
diately about the mine. The landslide forms a layer ranging in thickness
from a few feet to a maximum of at least 25 feet at the lower end of the
slide. The area surrounding the ore deposit appears to have been the
scene of many landslides covering a long period of time. The magnitude
of the 1937 landslide was probably increased by the removal of under-
ground material during mining activities. The area is still unstable as
indicated by a large crack in the lower end of the gray and green chert
outcrop, and the many cracks and joints in the bedrock and the soil.
Two other landslides near the railroad tracks occurred during the
winter of 1952-53 and temporarily blocked the tracks.
Alluvium
Alluvium is confined to the banks of the Eel River and consists of
sand, gravel, and rock debris deposited by the river during the winter
and spring high-water periods. The creeks and streams draining into the
Eel River, which have steep gradients and occupy narrow channels,
have deposited little or no alluvium along their banks.
STRUCTURE
The major structural feature of the Island Mountain region is a
homocline within beds of graywacke and black shale belonging to the
Franciscan group. The strike of the bedding of the graywacke and shale
is north-northwest and the average dip is 70° northeast. Paralleling
the general strike of the graywacke and shale are several notable faults
marked by depressions and in several localities by shear zones and
landslides.
A shear zone that may coincide with a significant fault is within the
graywacke just east of the area included on the geologic map of the
mine area. This fault is marked by a general depression traceable
northward over the mountain for several thousand yards, by two small
landslides, and by two springs which flow during most of the year.
Southward the fault can be traced as far as the west side of the area
mapped. Another fault within the graywacke is on the north slope of
the mountain near the northern end of the railroad tunnel. This fault
has a strike of N. 30° E. and a dip of 70° to the northwest. Displace-
ment on these faults could not be determined.
Nos. 1 and 2] island mountain mine, trinity county 17
The only structure visible in the shale beds is west of the north end
of the railroad tunnel, where the shale beds are offset as much as 3 feet
by several small faults. Several drag folds are also visible in the shale
at this location.
Associated with the graywacke and shale are isolated lenses of chert
and glaucophane schist that are probably the remnants of continuous
belts broken up by faulting1. The strike of the bedding of the red and
brown radiolarian chert and glaucophane schist mass cropping out
above the Island Mountain mine is parallel to the enclosing gray-
wacke; however, the dip of the bedding is vertical. The strike of the
bedding of the large body of gray-green chert on the east side of the
mine is N. 10° E. and the dip is 65° W. This chert appears to have
overturned and rotated slightly and to have moved downslope some
distance.
Intruded into the graywacke are several bodies of greenstone which
probably originated as plugs and dikes. Others appear to be remnants
of an extensive, thick sill, also intrusive into the Franciscan, which by
erosion has been dissected into the several isolated masses now ob-
servable on the summits of the region, with Franciscan rocks below
them on all sides. The flat-lying isolated masses of diabase and andesite
are also remnants of a sill or dike.
ISLAND MOUNTAIN MINE
History and Production
Mineralization was first noted in the Island Mountain mine area
sometime before 1897, when a spring with a high copper content was
found and named Poison Spring. Many medicinal properties were
attributed to the water; it was first used as a cure for sores on horses
and later was tried as a cancer cure.
About 1897, Sam H. Rice, who was making a survey of the boundary
between Trinity, Mendocino, and Humboldt counties, recognized copper
ore in the mine area. It was then that F. A. Leach, one of the founders
of the Island Mountain Copper Company, became interested in the
area. However, no mining was done at this time.
In 1889, the London Exploration Company was given an option on
the property. Company field engineers believed that the sulfide ore was
part of a wide vein that extended downward. A tunnel was driven
northward 490 feet from a point 50 feet north of the river bank, but
ore was not encountered. It was concluded that the ore body was not
part of a vein, and the project was abandoned.
A few years later, the U. S. Smelting and Refining Company sent
A. P. Anderson to examine the property. On the basis of his report, the
company took an option on the property, but did not do any mining.
In 1905 W. B. Devereau, Charles N. Felton, and associates, took an
option on the property and explored the deposit extensively. Several
shafts and tunnels were completed and numerous samples were taken.
However, no ore was mined and in the winter of 1905 the property was
abandoned.
The U. S. Smelting and Refining Company under A. P. Anderson
again became interested in the deposit, took another option, and did a
little work before they, in turn, abandoned the project.

The Northwestern Pacific railroad was completed in the fall of 1914
and, in April 1915, began regular scheduled operations. With a rail-
road nearby, the Island Mountain Consolidated Copper Company soon
began mining the deposit. The first three years of operation were car-
ried on in the shafts and tunnels driven by Devereau and his associates.
Mining operations were continuous from 1915 through 1930 with the
exception of the period from early in 1919 to the fall of 1922 when a
drop in copper prices caused the mine to close.
During the first months of mining the ore was pushed in cars across
a suspension bridge purchased from the Utah Construction Company
which had just completed the railroad tunnel. The ore was dumped
into an ore bin at the end of the bridge, loaded into a dump truck, and
hauled to a hopper on a railroad siding. However, during later opera-
tions, ore was conveyed on an aerial tramway from an ore bin at the
mine to a large storage bin on a railroad siding near the south end of
the Eel River railroad bridge. The ore was then sent to Tacoma, Wash-
ington for smelting.
Operations at Island Mountain ceased in the winter of 1930 when
the price of copper dropped. Although the mine was completely
equipped and ready to begin operations should the price of copper
increase, it was never put into operation again.
The huge landslide of 1937 completely buried the tunnels and shafts
with rock debris and mine dump material. The buildings and equip-
ment have either fallen into ruin or been carried off since the mine
closed.
In the 12 year period of activity, about 132,000 tons of ore were
shipped to the smelter. This ore averaged 3.296 percent copper, 1.092
ounces of silver, and 0.0651 ounce of gold per ton.
The accompanying table is a summary of the production record of
the mine from 1915 to 1930. The high copper content of the ore mined
during the first five year's operations was obtained by mixing high
grade ore from boulders of float, found on the edge of the river, with
the regular ore.

Geologic Units in the Mine Area
Graywacke, black shale, chert, and glaucophane schist, all belonging
to the Franciscan group, are the rock units found in the immediate
vicinity of the Island Mountain mine, together with unconsolidated
alluvium and landslide material. These rock units are shown on the
map, the cross sections, and the geologic plan of the underground
workings.
Ore Deposit
General Character and Distribution. The known ore deposit at
Island Mountain is a large body of massive sulfide containing pyrite,
chalcopyrite, pyrrhotite, and minor proportions of arsenopyrite, galena,
sphalerite, cubanite, bornite, and magnetite. Gold and silver occur in
recoverable amounts, probably in solid solution or as a mechanical
admixture in the chalcopyrite or pyrite.
The ore body blocked out before mining operations began in 1915
was kidney-shaped, trended in a northwesterly direction, and plunged
into the mountain at a low angle. The accompanying figure shows the
approximate outline of the ore body. The lowest part of the ore body
Nos. 1 and 2] island mountain mine, trinity county
21
was about 120 feet above the river. The ore body was 450 feet long
at the surface, 120 feet wide at the widest part, 140 feet thick, and was
estimated to contain 275,000 tons of ore (Leach, 1911, p. 2).
Below the main ore body and near the river was a huge boulder of
solid ore that was believed to have slid down from its original position
about 300 feet higher on the ridge. This boulder was 40 feet high and
contained about 5,000 tons of ore averaging 5 percent copper. Below
this boulder and nearer the river was another boulder weighing ap-
proximately 200 tons and containing about 20 percent copper. Smaller
boulders of float ore recovered from the lower part of the mine area
brought the total amount of float ore to about 8,000 tons.
The ore shown cropping out near the center of the immediate mine
area is believed to be part of the original large kidney-shaped ore body.
All that remains of the float ore are many small fragments of the
original boulders.
The minerals which constitute the ore body were deposited in the
shale and graywacke by a process of metasomatic replacement. The
boundaries of the ore visible at the present time grade off rapidly into
the country rock. Most of the ore body is remarkably deficient in gangue
minerals, such as quartz, and it is only where it has but partially
replaced the country rock that it can be said to have a gangue of
residual unreplaced shale.
The ore body and the surrounding crust of partially replaced shale
appear to be in fault contact with the enclosing black shale and sheared

graywacke of the Franciscan group. The structural relationship be-
tween the ore body and the country rock could not be ascertained be-
cause of the obscuring mass of landslide debris and the inaccessibility
of the underground workings. The following comments regarding the
boundaries of the ore body were made by A. C. Lawson (1918, p. 2-3)
when he visited the property and examined the underground workings
of the mine :
"The boundaries of the ore body as they are revealed in the mine workings are :
(1) the original footwall of the mass, (2) the original hanging wall, and (3)
various faults which have dislocated it.
The footwall is the upper surface of a zone of intense shearing and internal
movement. The softer rocks have been crushed and mashed to clay, and the harder
layers have been broken and pulverized by attrition, leaving many residual boulders
such as are common in fault gouges. The depth of this zone of crushed rock is
unknown but the condition is significant of a great fault, probably a thrust, which
makes a low angle with the horizon. The general strike of this fault is about
north-northwest to northwest and the dip is easterly. The ore does not seem to have
been involved in this great fault movement, and it is therefore fair to infer that the
fault itself was a dominant condition in determining the deposition of the ore.
Nos. 1 and 2] island mountain mine, trinity county
23
The original hanging wall of the ore body presents a notable contrast to the foot-
wall. The rocks above the ore are sandstones and shales as in the footwall, but
they have been affected by crushing, internal movement and gouging to a relatively
slight extent and in general are in their normal condition. No sharp wall marks
the transition from the ore to the hanging wall country, but the passage is grada-
tional through a rock with disseminated sulfides to the ordinary unmineralized
country rock. Both the hanging and footwall boundaries of the ore body dip in a
general way to the northeast, tho with undulations.
Besides the hanging wall and the footwall, there are several fault boundaries.
Where the faults dip under the ore they have been hitherto regarded as portions
of the regular footwall and where they dip away from the ores, as portions of the
regular hanging wall. From a miner's point of view, there is no objection to regard-
ing these faults as footwall or hanging wall as the case may be ; but the acceptance
of this view precludes the suggestion that the ore has been dislocated and portions
of it displaced above or below the level upon which the supposed original boundaries
are encountered. It is, therefore, important for the purpose of getting a line on the
possible extension of the ore body beyond its present known limits, to discriminate
between the original boundaries of the ore — the foot and hanging walls, and bound-
aries that may have been secondarily imposed by faulting. Several such bounding
faults were recognized in the course of my examination, as well as other faults
which traverse the ore body without establishing limits to its perceptive extent."
At the present time, there is no visible evidence of the secondary
faults mentioned by Lawson above.
Before mining operations began at Island Mountain, part of the
deposit was carefully sampled by assaying samples obtained by quar-
tering all of the ore extracted in the course of driving the exploration
tunnels and shafts shown on the preliminary underground map. The
assays showed copper ranging from half a percent to 27 percent with
3.14 percent a conservative estimate of the average. The sampled ore

copper content. The results obtained are shown below :

90,125 tons averaging 3.8 percent copper
Sufficient work was not done to estimate the value of the remaining
180,000 tons of undeveloped ore, but on the basis of many other assays,
it was believed that the remaining ore would run about the same as
the developed ore (Leach, 1911, p. 4). The average of 132,000 tons of
ore assayed and obtained in operation from 1915 to 1930 is as follows :
Copper 3.296 percent, gold 0.651 oz. per ton, and silver 1.092 oz.
per ton.
Mineralization. The primary metallic mineral assemblage of this
deposit, consisting of magnetite, pyrrhotite, pyrite, arsenopyrite, chal-
copyrite, cubanite, sphalerite, galena, and bornite is typical of deposits
that have been formed under conditions of fairly high temperature and
moderate depth. Magnetite and pyrrhotite are generally indicative of
high temperature. The association of pyrite, arsenopyrite, chalcopyrite,
sphalerite, and galena is common in many other types of deposits in-
cluding the low temperature epithermal deposits. However, the whole
assemblage is characteristic of Lindgren's (1933, p. 618) "pyritie re-
placement deposit ' \
Numerous supergene minerals have been reported from the Island
Mountain mine area. Several of these are believed to have resulted from
the oxidation of mine dump material containing sulfide minerals ; how-
ever, most of the supergene minerals are the result of secondary en-
richment. Secondary minerals obtained by the writer include : native
copper, chalcocite, chalcanthite, malachite, and azurite. Other secondary
minerals reported by others are : orpiment, copiapite, fibroferrite,
goslarite, halotrichite, melanterite, pisanite, roemerite, coquimbite,
bieberite, and morenosite. Gangue minerals include quartz, calcite, and
gypsum.
Primary Minerals. Pyrrhotite is the predominant metallic mineral
in the remaining part of the ore body examined by the writer. Gener-
ally the pyrrhotite is reddish tan and massive except in one or two
zones where small anhedral grains from 0.1 mm to 2 mm are found.
Typically the grains of pyrrhotite are so small that in polished sections
the mineral appears to be one solid mass. Near the upper part of the
ore body two types of banded ore are found. The first type consists of
bands of fine-grained pyrrhotite and pyrite running through massive
chalcopyrite ; in the other type, pyrrhotite occurs in small masses
roughly alined in bands with chalcopyrite and quartz. Most specimens
that appeared to be massive pyrrhotite, when examined with a hand
lens, were found to contain some chalcopyrite when studied in polished
sections. Several samples of pyrrhotite were checked for nickel and
cobalt but no nickel and only a trace of cobalt was found.

Pyrite, the next most abundant metallic ore mineral, is found in all
parts of the ore body. It is most abundant near the upper borders of the
mass of sulfide minerals. Most of the pvrite is pale yellow, anhedral,
and ranges in grain size from 0.1 mm to 1 mm. Euhedral crystals of
pyrite partly replaced by pyrrhotite and as much as 5 mm in diameter,
are abundant in the massive pyrrhotite. Near the outer limits of sulfide
mineralization pyrite is interstitial with shale fragments and is locally
finely banded. Pyrite also occurs as corroded veinlets in chalcoptyrite,
as layers of massive pyrite in chalcopyrite, as small masses of radiating
crystals which are possibly pseudomorphs after marcasite, and as
lamellar masses.
The most important copper mineral at Island Mountain is chalcopy-
rite, which is generally massive, and occurs as small blebs in pyrite
and pyrrhotite, as fine veinlets, and as large patches of nearly solid
chalcopyrite. Although chalcopyrite occurs throughout the deposit, it
appears to be concentrated in local zones where it is associated with
pyrite rather than pyrrhotite.
Magnetite was only found in some of the specimens and ordinarily
in minor proportions. In several specimens however, it was fairly
abundant. Most of the magnetite seen in polished sections was in the
form of small octahedrons, as much as 3 mm in diameter, embedded in
arsenopyrite. Because of the high magnetic qualities of some of the
specimens, magnetite may be finely disseminated in them.
Only one specimen containing arsenopyrite was available for study.
The exact location from which the sample was taken is unknown. In
this specimen arsenopyrite occurs as steel-gray bladed crystals as much
as 5 mm in length and associated with magnetite and chalcopyrite.
Cobalt has been reported 5 from ore of which this specimen is a repre-
sentative sample, but only a trace of cobalt was obtained by chemical
tests and no cobalt minerals were identified by polished section study.
The pale yellow mineral cubanite, identified in some of the polished
sections, is associated with chalcopyrite and pyrrhotite. It is ordinarily
in small blebs or irregular patches in chalcopyrite, and is found only
in specimens from the margins of the ore body.
Galena was not identified in hand specimens, but minor amounts were
found in several polished sections of samples obtained near the shale
contact. All the galena observed occurred as small blebs closely associ-
ated with chalcopyrite. The common grain size was in the range from
0.1 mm to 0.5 mm in diameter.
Interstitial to pyrite and pyrrhotite in several polished sections are
small patches and veinlets of sphalerite. All the sphalerite is dark gray
or reddish black and no doubt contains a considerable amount of iron.
Sphalerite does not occur in quantity and was not identified in hand
specimens.
Bornite appears in one polished section as small irregular patches in
pyrite, associated with chalcopyrite. This specimen was found near the
upper level of the ore body.
No gold, silver, or gold and silver minerals were found in any of the
polished sections studied. It seems very probable, therefore, that the
gold and silver are carried in one or more sulfide minerals either in
solid solution or as a mechanical admixture.

Supergene Minerals. The oxidized zone at Island Mountain has been
almost completely removed by landsliding. The only remaining- mass of
gossan material was found near the upper contact of the ore body with
the shale. No information was obtainable regarding' the original extent
of the gossan or its composition ; apparently there was no concentration
of gold or silver in the gossan as no gold or silver are present in the
remaining gossan.
The mass of oxidized material contains the following supergene min-
erals : chalcocite, native copper, chalcanthite, malachite, and azurite.
These minerals occur as coatings on the shale. Some of the native copper
occurs as thin partings between shale layers. Chalcocite may be the
original supergene mineral, and the other minerals forming as oxida-
tion products. Emmons (1917, pp. 176-177) gives several reactions
whereby chalcocite may oxidize to native copper, copper and iron sul-
fate, and sulfuric acid. This oxidation process possibly has taken place
at Island Mountain.
Claudetite is reported (Murdock and Webb, 1948, p. 113) as crusts
in the oxidized zone, but none was noted during the present study.
Claudetite also occurred as a sublimation product of fires on the dumps
containing arsenopyrite.6

Gangue Minerals. Gangue minerals occurring- with the sulfide min-
erals at Island Mountain are ealeite and quartz. Small veinlets of cal-
cite were observed in several polished sections of the ore. Quartz found
in nearly every polished section studied, occurs in two generations.
As an early mineral it fills the interstices between the sulfide minerals
and the partially replaced shale, and forms small patches in the massive
sulfide ore. The proportion of quartz is smaller in the massive sulfide
ore and greater in the partly replaced shale. Late quartz is usually
found as veinlets between and cutting across the sulfide minerals.
Fibrous gypsum fragments were found in several specimens of partly
mineralized shale from near the upper contact of the ore body and the
shale. The gypsum occurs as thin partings between the shale beds.
Paragenesis. The metallic minerals appear to have been deposited
in several stages. Earlier minerals have been transected and, in part,
replaced by succeeding minerals. A single ore specimen seldom, if ever,
reveals the whole history of mineralization of a deposit. Although the
lack of systematically collected specimens precluded a rigorous study,
a few good specimens selected from widely separated parts of the de-
posit suggest a general sequence of mineralization.
The first mineralizing solutions to enter the area were probably the
richest in silica, for silicification of the country rock is indicated in
most of the specimens examined. Magnetite seems to be the first metallic
mineral deposited. Pyrite was deposited next, but whether or not it
overlapped the magnetite in time of deposition has not been satisfac-
torily proven.
That the next four minerals, pyrrhotite, chalcopyrite, cubanite, and
sphalerite, are ordinarily closely associated in space is probably indica-
tive of a close association in time, also. They probably overlap in time
of deposition. However, both sphalerite and chalcopyrite cut pyrrhotite
in minute veins and do not show the reverse relationship. Cubanite was
found in two polished sections where it occurs as exsolution bodies in
chalcopyrite.
Minute blebs and local veinlets of chalcopyrite disseminated through
the massive pyrrhotite were observed in several polished sections and
suggest exsolution. At high temperatures pyrrhotite can hold consider-
able amounts of chalcopyrite in equilibrium in its structure. This mix-
ture is not stable at lower temperatures however, and if cooling is slow
enough the chalcopyrite forms little exsolution blebs (Hewitt, 1938, p.
319). This phenomena also can occur in the formation of chalcopyrite
and sphalerite and appears to have happened in these ores. In several
of the sections studied, chalcopyrite and sphalerite have developed
"mutual boundaries" with each other, suggestive of contemporaneous
formation. In one or two places it appears that chalcopyrite is replac-
ing sphalerite, which would indicate the persistence of chalcopyrite.
Although galena appears to be deposited contemporaneously with
chalcopyrite, most of the galena has replaced chalcopyrite.
Bornite and arsenopyrite are rare and were found in only one pol-
ished section and were not in contact with each other.
Because pyrite and quartz are found replacing chalcopyrite, at least
two generations of pyrite must be present. This pyrite represents a
later generation of pyrite than the pyrite which was replaced by pyr-
rhotite. Quartz, in turn, has replaced the late pyrite.

Gold and silver are omnipresent in these ores and are probably car-
ried by the pyrite or chalcopyrite.
Toward the end of mineralization, and probably with a lowering of
temperature, calcium carbonate wras introduced.
Chalcocite occurs along the boundaries of the bornite or as minute
veinlets cutting across the bornite. Chalcocite is clearly secondary in
origin and is altered to native copper and other secondary copper
minerals.
The accompanying chart shows graphically the time order of intro-
duction of the metallic and non-metallic minerals. This is a qualitative
diagram because it would be virtually impossible to assign quantitative
values to the various minerals.
Preliminary Magnetometer Survey
In October 1954, the writer with Gordon D. Bath of the Geophysics
Branch, U. S. Geological Survey, conducted a preliminary survey of
the immediate mine area with an Askania type magnetometer. Although
the primary purpose of this survey was to determine whether or not
a magnetometer could trace the outline of the ore body buried in land-
slide debris, enough time was available for several traverses near the
upper end of the landslide. During the course of these traverses, an
anomaly was obtained which may be indicative of another mass of
sulfide ore. The anomaly is located in an area where no ore minerals
were previously known to exist. Dr. Bath has provided the following
statement on the survey 7 :
"At the suggestion of Edgar H. Bailey, magnetometer measurements were taken
over the old workings of the Island Mountain mine by Gordon D. Bath and Melvin
C. Stinson on October 5, 1954 to determine the feasibility of using a magnetic method
of geophysical prospecting to detect the buried sulfide bodies that have a high per-
centage of magnetic pyrrhotite. The old mine workings are covered by talus and dump
materials, and the exact size and pyrrhotite content of the sulfide remnants are not
known. As shown on traverses A and B in figure 13, higher magnetic readings were
found over the inferred positions of remnants than over the adjacent graywacke
rocks. Still higher readings were found along the three traverses that are about 300
feet up the slope with highs that coincide with the projection of the mineralized zone.
Of the numerous pieces of rock float that were field tested for rock magnetization,
only the pyrrhotite-rich pieces were found sufficiently magnetic to produce the mag-
netic highs. The susceptibility of the more magnetic specimens was found to be about
0.0025 c.g.s. units. A dike-like body, 50 feet wide with this susceptibility magnetized
in the direction of the earth's field and buried to a depth of 10 feet beneath the mag-
netometer, would have to extend to a depth of 25 feet to produce a 250 gamma high,
or extend to a depth of 100 feet to produce a 550 gamma high."
Suggestions for Further Exploration
The structural feature that has been the controlling factor in the
localization of mineralization at Island Mountain is a shear zone that
extends through the mine area and occurs within the black shale. The
shear zone, which can be traced for several miles both northwest and
southeast of the known ore body, is the most likely structural guide to
other ore bodies. A survey using a magnetometer, gravimeter, or other
geophysical instruments may prove fruitful as might the use of geo-
chemicai methods such as analyses of soil, water and plants. Further
surface exploration would be hindered by the large amount of landslide
material covering the shear zone. Other shear zones are widespread in

the area and may possibly contain bodies of metallic ore minerals buried
by landslide debris and soil.
A characteristic of shear zone deposits cited by Butler (1948, p. 4)
is the relatively long- vertical extent of these deposits. The known ore
body at Island Mountain has a very short vertical extent (approx. 100
feet). The possibility that this ore body is only one of several ore shoots
extending: downward should not be overlooked in future exploration.
A. C. Lawson (1918, p. 4, 5), in his report on the Island Mountain
mine, mentioned that in the direction of its dip (east), the limits of the
ore body have not been reached by any of the mine workings. He further
stated that the boundaries against which the ore had stopped were faults
beyond which the ore may reasonably be expected to be found in dis-
placed positions. A survey by geophysical methods to the northeast and
east of the known ore body may reveal more ore buried at depth. This
survey should also be continued northwest of the ore body because the
secondary faults shown by Lawson (plate 4e) displace the northwestern
portion of the ore body upward and to the northwest (see fig. 10).

ABSTRACT
Mariposa County, embracing 1453 square miles of sparsely populated territory,
lies almost wholly within the Sierra Nevada. From the southwestern boundary,
where the terrain has moderate relief bordering the San Joaquin Valley, the county
narrows gradually eastward, becomes increasingly rugged and terminates at the
crest of the Cathedral Range — part of the glaciated wonderland of the High
Sierra. Famous as a gold-mining county from earliest gold-rush days, it is even
more noted for its vacationlands of Yosemite Valley, Tenaya Lake, Wawona and
Mariposa Grove of giant sequoias.
Approximately three-fifths of the county, from El Portal westward, is underlain
predominantly by complexly folded metasedimentary and metavolcanic rocks of
Paleozoic and Upper Jurassic age. East of El Portal it is underlain almost wholly
by late Jurassic or early Cretaceous granitic rocks. A thrust fault system formed in
Upper Jurassic time passes across the county from Mormon Bar northwest to
Coulterville. In general this fault system divides areas of Paleozoic and Upper
Jurassic rocks, Jurassic rocks lying chiefly west of the fault system and Paleozoic
rocks to the east. The fault system has been extensively mineralized by gold-bearing
quartz veins which form the famous Mother Lode. Important belts of vein-filled
fissures extend for 10 miles on both sides of the Mother Lode and certain fissure
systems paralleling the Mother Lode have been mineralized by base metals.
Although primarily a gold-mining country, gold is not the only mineral resource.
Substantial quantities of copper, lead, zinc, silver and tungsten have been found
in the county and production of base metals is particularly important in wartime.
The principal nonmetallic minerals are barite, limestone, dolomite, mica schist,
slate, granite, silica, and sand and gravel. More than 20 mineral commodities have
been produced in the county, recorded mineral production having reached a peak
in 1939 when $1,759,286 was realized from mineral materials. Current mineral
production is at the rate of between $200,000 and $300,000 annually.
Gold production, carried on almost continuously since 1848, has totaled more
than $24,000,000 since 1880. Total production, including that prior to 1880, al-
though imperfectly recorded, has been estimated at about $48,000,000. The most
productive mines have been the Hite, Princeton, Mount Gaines, Pine Tree, and
Josephine, Mariposa, Hasloe, Washington, Bandarita, Mary Harrison, Red Cloud
and Clearinghouse.

Silver, almost invariably associated with gold in the quartz; veins, has added
materially to the mineral wealth of the county. Mesothermal quartz veins carrying
silver sulpho-salts as the chief primary minerals are found in the Silver Bar and
Silver Lane mines near Bootjack.
Platinum, recovered in small quantities in the county from placer gravels, was
once the object of extensive search because it was reported to be present in quart*
veins near Bagby. No platinum was ever produced from vein sources and the oc-
currence has not been verified.
Tungsten is widely distributed in the eastern part of the county where it occurs
chiefly in limestone and allied carbonate rocks near their borders with intrusive
granitic rock. Tungsten deposits were being developed and exploited in the El
Portal district in 1954.
Copper mining, although currently inactive, has been important in several past
periods and considerable copper reserves remain in the county. Peaks in copper
production were reached in 1913 when 416,031 pounds was produced and 1942-1945
when more than 400,000 pounds was recovered.
Production of lead and zinc, which occur together, has been carried on principally
in wartime. The Blue-Moon mine produced 50,000 tons of ore averaging 14 percent
zinc in 1944-45. There has also been a small wartime production of chromium and
manganese ore.
Limestone, quartz, and barite are the three principal non-metallic minerals utilized
thus far. Nearly 1\ million tons of limestone were mined from deposits near Incline
by the former Yosemite Portland Cement Company for its plant at Merced ; these
deposits were not depleted ; the LeGrand quarry produced 147.964 tons of quartz
between 1942 and 1952 for use in the manufacture of ferrosilicon. The El Portal
barite mine was the source of 198,613 tons of barite between 1910 and 1948.
INTRODUCTION
Geographic and Cultural Features. Mariposa County was one of
the original 27 counties created by the State Legislature early in 1850.
It originally included most of Merced, Madera, Fresno, Kings, Tulare,
and Kern Counties as well as parts of Mono, Inyo, and San Bernardino
Counties (Laizure, 1928, p. 72). At present Mariposa County has an
area of 1463 square miles, is roughly triangular, and lies almost wholly
within the Sierra Nevada. The long direction of the triangle, oriented
northeast, measures about 65 miles, with the southwestern boundary
or base of the triangle roughly 35 miles in length.
Along the western edge of the county, which borders San Joaquin
Valley, the terrain consists of rolling hills of moderate relief. Toward
the northeast the surface becomes increasingly dissected and rugged
and relief becomes extreme in the ice-sculptured canyons of the
High Sierra east of Yosemite Valley. However, remnants of ancient,
low-rolling surfaces still appear in the central part of the county where
they stand far above the bottoms of the actively eroding river canyons.
Much of the arable land and upland pasture is found on these old
surfaces.
The county is drained chiefly by the Merced River and its forks,
although tributaries to the Chowchilla River drain the southwestern
part. Where the Merced River Canyon debouches onto the plain of San
Joaquin Valley, elevations are only 350 feet, but the canyon floor rises
to elevations of 4000 feet in Yosemite Valley, and the main stream has
its headwaters on Mt. Lyell in Madera County at elevations above
13,000 feet. Parsons Peak, the highest in the county, rises to 12,120
feet.
The population of Mariposa County, numbering slightly over 5100
by the 1950 census, is concentrated chiefly in Mariposa (the county
seat), in the Yosemite Valley resorts and in smaller towns scattered

along the two chief state highways (140 and 49). From 1907 to 1945
the county was served by the Yosemite Valley Railroad which followed
the course of the Merced River from Merced Falls to El Portal. Dis-
continuance of this line left the county without rail facilities. State
Highway 140, the all-year, all-weather route to Yosemite, is the only
road through the county adequately engineered for sustained heavy
trucking.
Prospecting and mineral exploitation is prohibited in Yosemite
National Park. Parts of the county east of Yosemite Valley have
proven too rugged and inaccessible to attract mining operators and are
largely devoid of mineral deposits. Mining is confined largely to the
western two-thirds of the county.
Historical Summary of Mining and Mineral Utilization. The early
mining life of the county was identified first with gold and second with
copper. Placer gold was discovered sometime prior to 1849, probably
by Spanish Californians. Agua Fria and Mariposa Creeks were among
the first to be worked. Before the end of the gold rush hardly a gulch
within the gold belt had been left unworked by placer miners, and the
piles of tailings they left can still be seen in most canyon bottoms.
What gold-bearing placer ground was left by these miners was later
worked by mechanized dredges. A small amount of platinum was pro-
duced as a by-product of gold-dredging operations. Discovery of lode
gold in Mariposa County is generally credited to Kit Carson and two

Kos. 1 and 2] mines and mineral deposits, mariposa county 43
associates who located the Mariposa mine in the spring of 1849. How-
ever, presence of early day arrastras suggest that the Spanish Cali-
fornians may have milled the first lode gold. By July of 1849 a stamp
mill had been erected and was processing ore from the Mariposa mine
(Logan, 1934, p. 184). A more elaborate stamp mill was built at the
Jenny Lind mine near Hornitos in 1851 (Bowen and Crippen, 1948,
p. 38). Although more elaborate crushing devices, such as the Hunting-
ton mill and various ball mills, were later developed and used exten-
sively in Mariposa County, use of stamp mills has persisted to the
present day.
Perhaps the greatest single influence on early-day gold mining in
Mariposa County was John C. Fremont's Spanish land grant, Las
Mariposas, containing 44,387 acres. Included in Las Mariposas was 12
miles of Mother Lode veins (extending from Merced River to Mari-
posa) as well as numerous other East Belt and West Belt properties.
Gold was discovered on the grant before Fremont had established clear
title to it and mines within its confines were involved in court actions
and even in bloody battles over a period of ten years after discovery
of gold. Largely unsurveyed and, because of grant title, not subject to
mining laws of the day, the mining properties had indefinite bound-
aries and are difficult to locate on maps to this day. The Mariposa
Mining and Commercial Company, organized by San Francisco finan-
cial giants Hay ward, Flood, Mackay, Jones, and others in 1887 (Brad-
ley, 1954, p. 32) took over the management of Las Mariposas and the
Company was not wholly liquidated until after World War II. In-
ternal dissension and inefficient management of the grant at some times
during its existence probably retarded development of its gold prop-
erties and lowered the total gold production of the county through the
years (Bradley, 1954, p. 32). Nevertheless, about 15 million dollars
was produced from mines of Las Mariposas, nearly one-third of the
estimated gold production of the county.
Another large property which figured prominently in Mariposa
County gold mining was the 20,000-acre Cook Estate astride the Mother
Lode in the Coulterville area. Operations of the Merced Gold Mining
Company which took over holdings of the Cook Estate in 1895 lasted
until near the close of World War I. The Cook Estate included most
of the prominent mines in the Coulterville area.
Copper was discovered in Mariposa County sometime during early
gold rush days but little or no mining of copper went on until 1863.
By 1868 (Browne, 1868, p. 218) there were three copper smelters in
Mariposa County, one each at James Ranch, Bear Valley and Hunter
Valley. A drop in the price of copper in 1868 ended the first period
of copper-mining activity. Other periods of activity in copper were
1901-1919 and 1929-1946. There have been few shipments of copper
ore in recent years.
Mining of other base-metals in Mariposa County has been carried on
largely during war years, although small amounts are produced inter-
mittently as by-products of gold mining. Government price supports
and the stockpiling program have stimulated some interest in strategic
minerals such as tungsten, chromium and manganese. Tungsten is the
most actively sought-for metal in the county with the possible exception
of uranium. Commercial deposits of uranium have not been found.
44 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
Mariposa County has contributed to the construction industry since
1850. Soapstone, quarried at Greeley Hill (Heizer and Fenenga, 1948,
p. 103) and used for building facings in Coulterville, and granite blocks
quarried at Mormon Bar and used in the Mariposa jail, are among the
earliest materials processed in the county. Many of the buildings
erected during gold rush days were built of slabs of field stone, avail-
able in most parts of the county. Production of roofing slate dates back
at least to 1897 (Aubury, 1906, p. 152). There are large reserves of
black slate of good quality in the county but throughout most of Cali-
fornia's history roofing slate has been unable to compete with lower-
cost roofing materials. A material increase in population of the Central
Valley towns might revive slate quarrying to supply flagstone and
allied materials. There is a small production for such purposes. Colored
materials for terrazzo chips and roofing granules are in considerable
demand. There is a small production of green serpentine for terrazzo
chips from a quarry north of Bagby.
Production of limestone began in Mariposa County in 1927 with the
opening of the Yosemite Portland Cement Company plant at Merced
(Merced County), and the establishment of quarries north of the
Merced River between Jenkins Hill and Incline. These quarries re-
mained active until 1944 when the Yosemite Valley Railroad ceased
to function. Limestone reserves were not materially depleted, although
more than 2,400,000 tons of limestone was removed.
Barite mines near El Portal produced throughout most of the period
from 1910 through 1948. The El Portal barite mine produced 398,613
tons of barite during this period, about 70 percent of the total Cali-
fornia production. Substantial reserves remain in the El Portal mine;
the mill is still functional and mining may well be resumed.
The existence of large numbers of veins of nearly pure quartz in
Mariposa County have attracted manufacturers of refractories and
ferrosilicon in recent years. From 1942 to 1952 147,964 tons of silica
was produced from the LeGrand (White Rock) silica quarry for use
in manufacture of ferrosilicon. There had been a small intermittent
production of silica prior to 1942 and a little has been mined since
1952.

GEOLOGY
General Geologic Features
The western two-thirds of Mariposa County is underlain chiefly by
metasedimentary and metavolcanic rocks of Palezoic and Upper Juras-
sic age. Among the metasedimentary rocks, slate, quartz-biotite hornfels
and quartz-biotite-graphite schists predominate, but there are some
large masses of limestone, chert, dolomite and quartzite. Metavolcanic
rocks are predominantly greenstones and green schists derived from
submarine-laid pyroxene andesite and basalt. All of these metamorphic
rocks have been intruded in late Mesozoic time by a variety of granitic
and peridotitic igneous rocks, among which biotite-hornblende grano-
diorite is the predominant type.
The eastern third of the county is underlain mainly by intrusive
granitic rocks of late Jurassic or early Cretaceous age varying in com-
position from hornblende gabbro to biotite granite. Hornblende biotite
granodiorite, biotite quartz monzonite and biotite granite are most com-
mon. The granitic suite of rocks is exceptionally well-exposed in the
walls of Yosemite Valley.
The metamorphic rocks in general form broad northwest-trending
belts. They are so distributed because they have been thrown into a
series of acute, commonly isoclinal, northwest-trending folds by com-
pressional forces acting essentially from the northeast and southwest.
The Mother Lode thrust-fault system which trends northwest across
the county from the vicinity of Mariposa through Coulterville, nearly
everywhere divides Paleozoic and Upper Jurassic rocks. Those east of
the fault system, although not studied in detail thus far, are largely
of Palezoic age whereas those to the west are Upper Jurassic. This
would indicate that the entire Upper Jurassic stratigraphic section,
which once aggregated at least 20,000 feet, has been uplifted and
eroded from the block lying on the east side of the fault. The Mother
Lode fault system in Mariposa County is not a single vein-filled fissure
but rather is a series of essentially parallel to en-echelon breaks. For
several miles in the Pefion Blanco district a single, vein-filled fissure
stands out from among all other veins in the area. In other parts of
the county the Mother Lode is hard to define. Many of the most pro-
ductive veins in the county are not directly related to the Mother Lode
fault system although they formed under similar conditions and at
about the same time.
Rock Units
Thus far the Paleozoic rocks have not been subdivided into units.
Turner and Ransome (1897, pp. 4, 5) described all of the metasedi-
mentary rocks of probable Paleozoic age in Sonora quadrangle under
the name Calaveras formation. More recently these rocks have been
referred to as the Calaveras group (Taliaferro", 1943, pp. 281-282). The

Paleozoic rocks in the very fine section exposed along the Merced River
east of Bagby probably could be divided into several slate and one or
more carbonate, chert and greenstone units. Carbonate rocks were the
only units separately mapped under the Calaveras formation by Turner
and Ransome.
Taliaferro (1943, pp. 283-285; 1951, p. 120) divides the Upper
Jurassic rocks along the Merced River west of Bagby into an upper
formation, the Mariposa slate, at least 6000 feet thick, and a lower,
predominantly volcanic series below it, the Amador group, totaling
nearly 15,000 feet. He subdivides the Amador group into five units,
oldest to youngest : the lower volcanics of unknown thickness, the pillow
Nos. 1 and 2] mines and mineral deposits, mariposa county 47
basalts (1200 feet thick), the Hunter Valley chert (lenticular, 950 feet
thick, maximum), the Pefion Blanco volcanics (chiefly greenstone,
9000+ feet thick) and the Agua Fria volcanics (3500 feet thick). The
Hunter Valley chert and the pillow basalt units thin out south of the
Merced River and neither are present in the section exposed along the
Mt. Bullion-Merced Falls road.
Calkins (1930, pp. 120-129) has subdivided the granitic rocks of the
Yosemite region into 13 units: the Johnson granite porphyry, Cathe-
dral Peak granite, Half Dome quartz monzonite, Sentinel granodiorite,
Bridalveil granite, Leaning Tower quartz monzonite, Taft granite,
El Capitan granite, granodiorite of the Gateway, biotite granite of
Arch Rock, diorite and gabbro, porphyry of Red and Gray Peaks, and
the Mount Clark granite. Rocks similar to these units occur elsewhere
in the county but are as yet unnamed and uncorrelated. In addition to
the rock types just listed there are small masses of gabbro, diorite,
quartz diorite, and olivine norite as well as lamprophyres and horn-
blende porphyries. All of these belong to the Jura-Cretaceous suite of
granitic rocks. Also belonging to this group is a rare dike-rock, albitite,
composed almost entirely of albite feldspar. In the Flyaway Gulch dis-
trict albitite is associated with quartz veins and in a few mines is the
host rock for gold-bearing ore-shoots.
Another important suite of intrusive igneous rocks, emplaced some-
what earlier than the granitic series but also of Upper Jurassic age,
is the peridotite group — most bodies of which are thoroughly serpen-
tinized. Saxonite and dunite were the principal types of peridotite
that formed prior to serpentinization, but within the large masses of
serpentinized peridotite are small segregations of gabbro, norite, pyrox-
enite, hornblendite and chromite. Two large, lenticular masses of the
serpentine rocks are found adjacent to the Mother Lode from Bagby to
Coulterville. The more southerly of the two extends north from Bagby
a distance of 6 miles and reaches a maximum width of about 2 miles.
Two groups of contact metamorphic rocks are worthy of special con-
sideration inasmuch as they are potential sources of economic minerals.
These are the contact-altered slates and carbonate rocks. Where large
masses of granitic rock have intruded slate, well-defined alteration
zones commonly develop. These are particularly conspicuous in western
Mariposa County. Approaching a granitic contact there is a regular
progression from uniform slate as follows:
Stage 1. Spotted slate with small dots of biotite mica, cordierite or quartz,
singly or together.
Stage 2. Knotted, glossy slate or phyllite with larger clots of the above min-
erals and (or) indistinctly formed chiastolite or well-formed anda-
lusite crystals in a groundmass characteristically containing sericite
mica and graphite.
Stage 3. Spotted to knotted schist with well-crystallized, micaceous groundmass
material plus large clots or large crystals of andalusite, cordierite,
quartz, etc.
Stage 4. (Nearest the granite) Dense, horn-like rock, called hornfels made up
chiefly of small, irregular-shaped crystals of quartz and biotite with
minor sillimanite or andalusite.
Some andalusite-bearing slates and schists in western Mariposa County
are possible sources of refractory aluminum silicate.

Silicated zones have formed along contacts where granitic rocks have
invaded carbonate rocks ; they commonly contain suites of calicum and
magnesium-bearing minerals such as garnet, diopside, epidote, tremolite
and wollastonite. It is in such mineral assemblages, called tactite rock
or skarn rock, that tungsten minerals most frequently occur. Most of
the promising tungsten deposits in the county are in rocks of this sort.
Tertiary rocks are found in Mariposa County in isolated patches
only. Erosion remnants of the middle Eocene lone formation are found
along the western border of the county in the vicinity of Merced Falls
where they do not exceed 100 feet in thickness. Coarse, red sands and
gravels, coarse white- to cream-colored andalusite-anauxite sands and
a little fine, white quartz sand are the conspicuous rock types in the
lone formation in Mariposa County. Three isolated patches of Eocene
river-channel gravels have been found in the county, two astride the

The most important Quaternary deposits are the glacial moraines
scattered through the eastern part of the county and the lakebeds on
the floor of Yosemite Valley. Isolated patches of terrace gravels are
found along the Merced River and its tributaries.
Geologic History
The earliest record upon which to base the geologic history of this
part of the Sierra Nevada lies in the Paleozoic metamorphic rocks.
These are marine sediments and possibly some submarine volcanic
rocks indicating that marine waters covered the land for a long period
of time A thick sequence of shale, limestone, chert (m some places
manoaniferous), sandstone and andesitic volcanic rocks accumulated
which later was transformed by heat and pressure into the slate,
crystalline limestone, metachert, quartzite and greenstone seen today.
Inasmuch as the degree of metamorphism is greater among the

Paleozoic rocks than among the younger Jurassic rocks, two meta-
morphic episodes may have taken place, and the crustal motion in-
volved in the first episode may have raised the Sierran area above
sea level.
Triassic rocks are unknown in the Mariposa County portion of the
Sierra Nevada. The base of the Amador group rests unconformably on
Paleozoic rocks, showing that a period of erosion preceded deposition
of the Jurassic rocks. Consequently, much of the area of the Sierra
Nevada must have been above sea level and actively eroding during
Triassic and Lower Jurassic time. By Middle Jurassic time much of
the Sierran area had again fallen below sea level, and 15,000 feet of
predominantly submarine volcanic material was piled onto the old
erosion surface. The manganiferous cherts originated as sea floor chem-
ical precipitates from a volcanic source and became interbedded with
the volcanic sequence. Part of the Mariposa formation, which is essen-
tially slate, was laid down during the waning period of volcanism, and
locally the lower part of the formation contains interbeds of volcanic
material. Most of the 6000-foot thickness of the Mariposa formation
is, however, a monotonous sequence of graphitic slate derived from
organic clay shale, and its homogeneity is broken only locally by lentic-
ular sandstone and conglomeratic layers.
Following deposition of the Mariposa formation, the series of crustal
disturbances began which resulted in rise of the ancestral Sierra
Nevada. Prior to warping of the rocks above sea level, the marine
sedimentary and volcanic deposits were invaded by dikes, sills, and
irregularly shaped masses of peridotite. These were either serpentinized
Xos. 1 and 2] mines and mineral deposits, mariposa county

as they were emplaced or were altered soon after. Chromite deposits
were formed as segregations in the original peridotite. The ancestral
Sierra Nevada, less lofty than the current mountain chain, nevertheless
covered a much broader area, extending at least half way across what
is now our Central Valley. During folding, large masses of granitic
rock were emplaced in the core of the range. The crustal deformations
involved in the folding resulted in deep-seated fracturing and faulting
of the metamorphic roof rocks as well as the outer granitic core. Thus
part of the vapors and solutions given off at the time of invasion of
the granitic rocks could rise upward and be deposited in the fractures.
Such is the origin of the gold-, silver-, copper-, lead- and zinc-bearing
veins in Mariposa County.
A long period of erosion followed the rise of the ancestral Sierra
Nevada. During this time the mountains were greatly reduced in ele-
vation and in area, the metamorphic roof -rocks being deeply eroded, and
the veins and ultimately the granitic core of the range laid bare. Gold
and the other heavy minerals of the veins and roof rocks became con-
centrated in stream deposits or in deltaic deposits at the edge of the
western sea. Erosion of the rocks was aided greatly by the chemical
decomposition characteristic of tropical climates, tropical conditions

having slowly developed at the end of the Cretaceous period as eleva-
tions were reduced. Middle Eocene deposits are, therefore, of the sort
produced by chemical weathering — quartz-andalusite-anauxite sands,
kaolinite-type clays and the like. These are very sparsely represented
in Mariposa County.
Still more sparsely represented are remnants of the Mio-Pliocene
period of volcanism, which literally overwhelmed the Sierran province
with volcanic debris. In Miocene time the range was again raised by
warping and faulting, and numerous volcanoes broke out along the
crest. These erupted rhyolitic ash first and then enormous volumes of
andesitic fragmental material and flow-rock. Old stream systems were
obliterated under piles of volcanic debris and new systems had to
evolve. Eocene gold-rich stream deposits were buried under the vol-
canic mantle and were thus protected from later erosion — to survive
to the present day. Volcanism continued intermittently into the Pleisto-
cene with extrusion of flows of basaltic aspect and latitic composition.
Late in the Pliocene great faults developed east of the former crest
of the range and highlands bordering the present Sierra began to drop
down, probably accompanied by some re-elevation of the range-crest
by tilting and by rise of fault blocks (Hudson, F. S., 1955, pp. 835-
869). This faulting continued through the Quaternary along the east
side of the Sierra Nevada and is going on today.
The tropical climate of Eocene time had gradually cooled to a tem-
perate one by Mio-Pliocene time. This cooler trend climaxed in the
Pleistocene with development of the alpine type of valley glaciers.
These sculptured the High Sierra into the form we see it today.
Throughout the Pliocene and Pleistocene epochs, great river systems
carved the deep, V-shaped canyons so characteristic of the western
three-fourths of the Mariposa County landscape. Although erosion has
largely eaten away such early gold-placer deposits as once may have
existed in the county, active erosion and temporary stream deposition
are responsible for accumulation of the placer deposits so important
to the early life of the county. Exhumed remnants of early Tertiary
land surfaces yield most of the arable land and gently rolling pasture
land in the county.

MINES AND MINERAL DEPOSITS
Statistical Summary
The recorded value of minerals produced in Mariposa County from
1880 through 1954 has amounted to $33,516,967. Gold production has
amounted to approximately 71 percent of this total — $23,837,047, ex-
clusive of 1951. Inasmuch as the estimated total gold production to
date has been about $48,000,000 (Bradley, 1954, p. 32), it follows
that approximately $24,000,000 in gold was produced prior to 1880.
The estimated total mineral production, therefore, is more than
$57,548,000, gold accounting for 83 percent of the estimated total.
The table on pages 40-42 lists the mineral production of the county by
year and commodity from 1880 through 1954. Items listed under unap-
portioned include those wherein producers numbered less than three.
In addition to the commodities listed in the table, 398,613 tons of
barite valued at $2,760,493 was produced in the county between 1910
and 1948 and 2,430,842.5 captive tons of limestone was quarried in
the period 1927 to 1945. The value of the limestone and barite is in-
cluded in the unapportioned list.

The principal deposits for which the authors were able to collect con-

of the county will be found in the tabulation which follows the text.
All mines known to the authors are covered in the tabulation.
METALLIC MINERALS
Ch
romium
Chromium most commonly occurs in the mineral chromite
(FeCr204), and in California is found in economic accumulations only
in peridotite or its alteration products. Chromite may occur as a
massive segregation in peridotite or it may be disseminated in grains
or pebble-shaped clots in a matrix of magnesian silicate minerals. Ore
is generally classed as massive, disseminated or leopard, leopard ore
being clots of chromite in a serpentine matrix. All of the known oc-
currences in Mariposa County are of massive type, but masses of ore
seldom exceed a hundred tons. According to Cater (1948, p. 8), large
concentrations of chromite are found only in dunite, a variety of
peridotite made up chiefly of olivine. Most of the peridotite in Mari-
posa County is the variety saxonite, containing abundant enstatite as
Nos. 1 and 2] mines and mineral deposits, mariposa county 61
well as olivine. Serpentinization is well advanced in all of the Mari-
posa County peridotite masses.
The two main masses of serpentine, elongated in a northwesterly di-
rection to the Mother Lode, stretch almost continuously from Mt.
Bullion north through Coulterville and across the northern county
boundary. A maximum thickness of about 2 miles is attained by the
more southerly of the two main masses just north of Bagb}^. A narrow,
northwest-trending belt of serpentine is also present adjacent to the
north bank of the Merced River a few miles northwest of Bagby.
Chromite has been mined on three properties in Mariposa County,
all active during World War I. The following excerpts are from Cater
(1948, pp. 14-15) who abstracted the material from unpublished war-
time reports by N. L. Taliaferro.
Fossow Property (1). "The deposits on the Fossow property are
in the NEJ, sec. 29, T.2S., R.16E., immediately at the crossroads known
as Penon Blanco, about 3 miles by road northwest of Coulterville. The
only ore found occurred as float plowed out of the deep soil covering
a small flat near the crossroads, and was on the west side of a small
draw near the west contact of a highly sheared serpentine mass. At
the time of Taliaferro's visit in 1918, about 600 pounds of such ore
had been recovered, but none was ever shipped." (The property ap-
parently is now part of patented claims owned by Oro Rico Mines Co.,
c/o A. D. Vencile, Room 14, 1584 Washington Boulevard, Los Angeles).
Reed Property (2). "The deposit on the Reed property is on Blacks
Creek, 1 mile southeast of the Fossow deposits in SWJ, sec. 27, T.2S.,
R.16W. Workings consist of a few trenches and a small open cut about
4 feet deep. The ore occurred as very small lenses striking N.40° W.,
parallel to the schistosity of highly sheared serpentine country rock.
This deposit, like the Fossow deposit, is near the west contact of ser-
pentine with Mariposa slates. At the time of Taliaferro's visit in 1918,
about 600 pounds of medium-grade chromite had been mined and a
small amount of ore was in sight in the cut." The property now is
part of the holdings of Walter J. Lautenschlager, 626 So. Catalina
Street, Los Angeles 5, California.
Riverside Chrome Mine (Pur cell-Griffin) (3). "The Riverside
chrome mine is about 3| miles south of Coulterville in the NEJ, sec. 22,
T. 3 S., R. 16 E. The deposit was located and worked by T. C. Purcell
who shipped 32 long tons of ore from it in 1918. Workings consist of an
east-trending open-cut 15 feet long and 8 feet deep, at the end of
which is a pit 4 feet by 6 feet [in plan] and 10 feet deep. The ore con-
sisted of an irregular lens of chromite striking about N. 80° W., near
the north end of a narrow serpentine mass. Near the workings the ser-
pentine is soft and highly sheared, but a short distance west of the pit
it is more compact and contains fine streaks and disseminated grains of
chromite. The schistosity of the serpentine in the vicinity of the work-
ings strikes N. 25°-30° W., at an angle to the attitude of the ore body.
No ore remained in sight in the workings at the time of Taliaferro's
visit, and it is assumed the deposit was exhausted." The property is
on or adjacent to the Adelaide gold mine, a patented property owned
by Alfred W. Stickney, 435 Hillcrest Road, San Mateo, California.

Copper
Mining of copper in Mariposa County is confined at present to small-
scale, intermittent activity with occasional small shipments of oxidized
ore. Some shipments of gold ore contain recoverable copper and there is
a small supplementary production from this source. The recorded pro-
duction of copper since 1880 is about 2,205,000 pounds valued at $344,-
500. Although there was some unrecorded production in the 1860s the
total copper mined in the county prior to 1880 was probably small. As
the total production of copper in California has amounted to about
600,000 tons (O'Brien and Crosby, 1950, p. 308) the amount of that
total contributed by Mariposa County has been less than 1 percent.
The primary copper deposits in Mariposa County are all of meso-
dermal origin and may be divided roughly into three classes: those
where copper is a by-product of gold mining, those where copper, zinc
and lead minerals are associated, and those in which copper ore-minerals
predominate. However, most copper ores contain some gold and silver
and many gold ores contain some copper so that the classes are grada-
tional. Copper ore is generally concentrated in shoots in shear zones
which cut a wide variety of wall rocks. Quartz or quartz and barite and
pulverized wall rocks are the common gangue materials. The principal
copper mines occur in northwest-trending belts that roughly parallel
the Mother Lode vein system. Although the copper deposits are probably
not directly related to the more extensive gold-quartz veins — some can
be demonstrated to have formed earlier than some of the gold deposits —
the structures which allowed egress to the mineralizing solutions of both
gold and copper formed during the same orogenic period, and both
metals are believed to have stemmed from solutions given off during
late-stage cooling of the intrusive granitic rocks. The various theories
of origin of the copper in the Sierran foothills are covered bv Hevl
(1948, pp. 25-28).
Most of the copper and zinc-copper mines are concentrated in three
narrow belts, each trending roughly N. 35° W. The most southerly be-
gins in the vicinity of Green Mountain School and extends somewhat
northwest of White Rock ranger station. Principal mines in this group
are the Green Mountain group, Lone Tree, Cavan-San Jose Great North-
ern and Pocahontas. A second belt, chiefly zinc-copper-lead mines, ex-
tends from somewhat northeast of Hornitos to Exchequer Dam. The Blue
Moon and American Eagle mines are the principal examples of this
group. A third belt of copper mines is in Hunter Valley between Cotton
Creek and Jasper Point on the Merced River. The La Victoria and Bar-
rett mines are the principal copper mines in this district. The Blue Moon
and Pocahontas mines are by far the largest copper producers in the
county but the Blue Moon mine is primarily a zinc mine. Gold mines
which have produced notable amounts of copper are the Mount Gaines,
Washington and Pine Tree and Josephine.
Barrett (Baretta, Barette, Beaudry) Mine. Location: Sees. 29, 30,
32, T. 3 S., R. 16 E., M.D., in hill land at the northern end of Hunter
Valley. Accessible from the paved Bear Valley-Hornitos road by 3|
miles of paved road and 4^ miles of graded dirt road. Ownership : An-
gelo Beaudry and Inez Bouvier, 1431 Moraga Street, San Francisco,
California, own three patented claims, the Wildcat, Mountaineer, and
Nos. 1 and 2] mines and mineral deposits, mariposa county 63
New Year, and a rectangular piece of land known as Berettas Enclosure
which includes most of the old Barrett and Beaudry claims.
The Barrett mine is a very old property discovered during the 1860s
(Aubury, 1905, p. 215). It was owned in 1902 by Joseph Baretta
(ibid.) and at that time had a shaft 200 feet deep. More than $90,000
had been realized from the mine up to 1907 (Lang, 1907, p. 966) most
of this amount having come from a pocket of coarse gold. In 1920 the
property was under lease to C. H. Burt of Mountain View (Castello,
1920, p. 102) and by that date a tunnel had been driven northeast to
intersect the northwest-trending ore zone. For a short period during
1931-32 it was mined by D. Jacobs of Coulterville and produced 100
tons of high-grade gold ore from which 70.7 oz. of gold and 16 oz. of
silver were recovered (U. S. Bureau of Mines records). In recent years
the mine has been idle and there is no equipment on the property.
The Barrett mine is among a large group of mines and prospects that
include the Castagnetto, Bruschi, Ferrari, Oaks and Reese and Iron
Duke mines. Many of these mines and prospects contain both gold and
copper, probably as the result of separate mineralization. The Barrett
has produced pocket gold ore and gold ore of milling grade as well as
high-grade, oxidized and sulfide copper ores. Upper parts of the pres-
ent, partly caved workings, apparently on the Wildcat claim, expose a
copper-stained quartz vein 1 to 2 feet wide, striking N. 60° to 65° E.
and dipping 65° southeast. Lang (1907, p. 966) describes banded vein
matter composed of alternating bands of calcite or calcite and barite
and quartz. Pyrite and chalcopyrite more or less impregnate the vein
matter in unoxidized parts of the veins. Some massive sulfide ore show-
ing some malachite was on the dumps on the Wildcat claim in Septem-
ber 1954. Lang (1907, p. 966) mentions vein structures trending N.
15° W. and there are probably two sets of mineralized structures. Soil
cover is heavy and the area is brush}'. Wall rocks are chiefly meta-augite
andesite greenstone although chert has been described in the workings.
No chert was present on the dump. The greenstone is part of the Penon
Blanco member of the Upper Jurassic Amador group of rocks (Talia-
ferro, 1943, pp. 282-284). Rhythmically banded chert and associated
sedimentary rocks of the Hunter Valley chert member of the Amador
group, exposed along the road south of the Barrett mine, strike N. 40°
W. and dip 63° northeast and it is assumed the enclosing greenstones in
general follow a similar trend in this area.
Blue Moon (Blue Cloud, Red Cloud, Porcupine) Mine. Location:
Sees. 19, 30, T. 4 S., R. 16 E., M.D., 6 miles north of Hornitos. Owner-
ship : Not determined. Last operator was Hecla Mining Company, Wal-
lace, Idaho (1945).
The Blue Moon mine is primarily a zinc mine but produced a notable
amount of copper. 55,656 tons of ore milled in 1944-45 yielded 406,038
pounds of copper, 13,687,920 pounds of zinc, 553,753 pounds of lead,
3,446 ounces of gold and 208,965 ounces of silver (Eric and Cox, 1948,
p. 145). The mine is more fully discussed under zinc.
Good View (Cavan, Cavan-San Jose). Location: 3 miles west of
Green Mountain School in sees. 5, 8, 9, T. 8 S., R. 18 E., and sec. 32,
T. 7 S., R. 18 E., M.D. Ownership: Mine-Metal Properties, Inc., c/o
C. C. Kellogg, 50 Twenty-sixth Street, Merced, California, owns 161.3
64 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
acres of patented land including- the following claims: Copper King,
Crown Point, Good View, Little Giant, Rothschild, San Jose, Stonewall
Jackson and Sunset. Accessible from Green Mountain School by 2\
miles of graded dirt road and 1^ miles of truck trail.
The Good View mine is an old property discovered in the early
1860s (Lowell, 1916, p. 573). Little is known of its history until the
period of operation by Cavan Mining and Milling Company of Stockton
from about 1900 to 1910. It was then known as the Cavan Copper Mine.
According to old U. S. Bureau of Mines records, 22 tons of ore was
shipped from the Good View claim in 1902 which yielded 8,673 pounds
of copper, 8 ounces of silver and .87 ounces of gold. In 1907, 45 tons of
ore yielded 4,624 pounds of copper and 1.21 ounces of gold. By 1913
the property had passed into the hands of S. L. Pearce who shipped
7 carloads of ore to the Selby, California, smelter which averaged
$1000 per car (Lowell, 1916, p. 573), the ore carrying $2.50 in gold
per ton (at the price of gold then). By 1927 the mine had passed to
the ownership of Samuel L. Thrift, et al., of Stockton and patent had
been acquired by the property (Laizure, 1928, p. 125). Since then the
mine has been known as the Good View. The property has been idle
for a considerable period and all equipment had been removed (1954).
Workings are driven chiefly in black slate, mica-andalusite schist
and blue-black quartz-biotite hornfels, all derived from clay shale, and
schistose metadiorite (?) intrusive into the metasediments. Some thin,
lenticular beds of metavolcanic material, probably tuff, are interbedded
with the metasediments in minor amounts and some metasandstone is
included in the slate. The metamorphic sequence is part of the Mariposa
formation of Upper Jurassic age. Regional trend of the folds in the
metasediments is northwest and the fracture systems along which ore
has developed also trend northwest.
As most of the workings have no means of access or are watered, and
as individual workings and claim boundaries are difficult to identify,
the workings can only be described in a general way. In 1902 a tunnel,
then 240 feet long, was being driven to intersect the parallel Rothschild
and Good View veins. This tunnel was estimated to strike the Good
View vein at a depth of 375 to 400 feet and the Good View at 250 feet
(Aubury, 1905, pp. 207-208). A 20-foot shaft at the south end of Good
View vein is also mentioned which followed a 6-8 inch streak of ore
running 15-25 percent copper. This streak was traceable on the surface
for 1400 feet. The main shaft, apparently on the Good View claim, was
described as 140 feet deep, exposing- a vein 6 inches to 6 feet wide. Ore
was described as oxidized to a depth of 75 feet with massive sulfides
below 75 feet. (Azurite, malachite and chalcopyrite are the chief ore
minerals in the district.) Aubury (1905, p. 208) also mentions a 58-foot
shaft on the Sunset claim, exposing ore containing 17 percent copper
from 10 feet below the surface to the bottom of the shaft in widths of
6 to 30 inches; a 20-foot and a 60-foot shaft and a 65-foot crosscut
tunnel on the Copper King claim (no drifts) ; and a cross-cut tunnel
170 feet long on the San Jose claim from which three winzes 40, 80,
and 115 feet deep had been sunk. The San Jose workings developed an
ore body 65 feet long and 4 to 4^ feet wide and at least 115 feet deep.
Surface work only had been done on the Crown Point, Stonewall Jack-
son, and Little Giant claims.

Green Mountain (Copper Mountain, Legioneer, Copper Queen)
Group. Location: Sees. 3, 10, T. 8 S., R. 18 E., M.D., 2 miles north-
west of Green Mountain School. Ownership: Dr. Felix A. Smith, 507
Medical Building, Oakland 12, California, owns 11 unpatented claims,
the Amador, Copper Chief, Copper King, Copper Mountain, Copper
Peak, Discovery, Francisco (Frisco), Green Mountain, Juliet, and Last
Chance. The Copper Queen and Buena Vista patented claims are owned
by Marie D. Kellogg, et al. Q), 50 Twenty-sixth Street, Merced, Cali-
fornia, and Dr. Felix A. Smith (J).
Croppings of copper ore were found in the Green Mountain area in
1861 (Lowell, 1916, p. 572) and the claims were worked intermittently
between 1863 and 1900. From the early 1900s to 1923 the property was
owned and intermittently worked by the Legioneer Gold Mining Com-
pany, O. R. Sydney, et al., of LeGrand or their authorized lessees.
The Legioneer company also worked the Lone Tree mine in the early
1900s. During 1903, 170 tons of ore was shipped which yielded 14,245
pounds of copper. In 1904, twenty tons of ore were shipped from which
9,500 pounds of copper was extracted (IT. S. Bureau of Mines records).
These figures are believed to be representative of the amount and type
of ore shipped at various times during the early 1900s but are not the
only shipments made. In 1919 the United Chemicals Company of San
Francisco completed construction of a leaching and precipitation plant
at Raymond, Madera County, to process ore from the Green Mountain
mines. Copper oxide, copper sulfate and iron sulfate were produced
in this plant, the average ore treated running 6 percent copper (Cas-
tello, 1921, p. 103). The Legioneer company continued to operate the
mine while the Raymond plant was in operation, O. R. Sydney acting
as superintendent. From 1923 to about 1929 the properties were oper-
ated by the Floraferro Company of San Francisco. This company sold
pulverized, oxidized ore as a soil additive and insecticide. The Copper
Producers Trust of Boston, Massachusetts, held title to the properties
for a while in the late 1920s.
Ore bodies occur as replacements in schist along irregular-shaped
shear zones, a majority being oriented roughly northeast with steep
dips toward the southwest. The schist is cut by dikes and irregular
intrusions of granitic rocks. Ore in the upper or oxidized parts of the
shoots contains various combinations of the minerals, malachite, azu-
rite, chalcocite, cuprite and native copper. Primary ores in the lower
parts of the shoots are made up chiefly of chalcopyrite and pyrrhotite.
Veins and irregular replacements adjacent to veins occur over a width
of as much as 1200 feet and some masses of sulfide ore reach a width
of 60 feet (Aubury, 1902, p. 253). Much of the ore proved difficult to
handle because it crumbles and heats upon exposure to air (Aubury,
1905, p. 254).
There are more than 4,000 feet of underground workings on the
property (Castello, 1921, p. 103) including numerous openings to the
surface. Aubury (1905, p. 204) states ". . .the most important (open-
ings) are two tunnels several hundred feet in length, above which are
the stopes and chambers from which the best ore has been taken. The
lower or east tunnel is in 600 feet (1902). At about 400 feet it has
crosscut a vein 60 feet in width. . . . The main body of ore lies back of
this, the openings or workings of which are about 60 feet above the
3—49184
66 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
tunnel level, to which they are all connected with an upraise. . . . About
900 feet west from the above tunnel and 50 feet above it, another
tunnel has been run several hundred feet, and from it a large quantity
of carbonate and sulfide ore has been extracted . . .".
Johnnie Green (Green, Johnny Green, Johnny Green Jr.) Mine. Lo-
cation : NEi, sec. 31, T. 7 S., R. 18 E., M.D., accessible by 4£ miles
of truck trail from the graded LeGrand-White Rock (Ganns Creek)
road or by 3J miles of truck trail from the graded Green Mountain
School road. Ownership : undetermined.
There is little record of the early history of this mine. In October
1866, fifty men were employed at the mine and about 50 tons of copper
were smelted and shipped per week (Min. and Sci. Press, vol. 17, no.
17, p. 262, 1866). In 1907 high-grade copper ore was still being mined
which was described as massive chalcopyrite replacing schist (Lang.

The mine workings are in a belt of quartz-mica and quartz-miea-
chiastolite schist, the schist being derived by contact metamorphism of
clay shale of the Mariposa formation of Upper Jurassic age. The strike
of the schist is N. 30° -40° W. and the dip is roughly 60° northeast.
Primary ore consists of chalcopyrite and pyrite or pyrrhotite impreg-
nating schist in replacement masses bordering narrow quartz veins.
There is some carbonate ore in the upper parts of the shoots.
A shaft of undetermined depth inclined 60° northeast is the prin-
cipal working but there is a second shaft opening 75 feet northeast of
the main shaft, also inclined 50°-60° E., but partly caved and of un-
known depth. North of these workings, several hundred yards, is a
second group consisting of 2 inclined shafts and a caved tunnel driven
about N. 20° W. The workings have no means of access and there was
no equipment on the property in September 1954. A small shipment
of oxidized ore was shipped from this area in 1954, but the authors
were unable to determine which property the ore was from.
La Victoria (Victoire, La Victoire, Tandem) Mine. Location: Sees.
4, 9, 10, T. 4 S., R. 16 E., M.D., in Hunter Valley, 11 miles by graded
road north of Hornitos. Ownership: Ralph E. and Libbie N. Dailey,
1165 West 22nd Street, Merced, California.
The La Victoria Copper Mine was thoroughly investigated by Man-
ning W. Cox and Donald G. Wyant of the U. S. Geological Survey
as part of the wartime research on the copper-zinc belt of the Sierran
foothills. The results of this investigation were published in 1948 by
the California Division of Mines on pages 127-132 of Bulletin 144, en-
titled " Copper in California." The following discussion is largely
abstracted from this source.
The La Victoria deposits were discovered in April 1864 and explored
by the La Victoria Mining Company. This company and its successors
mined and sorted high-grade ore for direct shipment to smelters and
also constructed a small furnace on the property to treat low-grade
ore. By 1873, most of the readily accessible ore had been removed and
the mine was shut down. Some ore was shipped during the 1890 's and
in 1917. From May 1943 to March 1944 the mine was under lease
from the owner, Herbert Lang, by R. B. Lamb. During this period the
Nos. 1 and 2] mines and mineral deposits, mariposa county 67
mine workings were partly rehabilitated and the property was sampled
with the aid of a R.F.C. loan. Since that time the mine has been inactive.
Mine workings are driven in meta-augite andesite greenstone which
has prominent pillow structure. The pillows range in diameter from
a few inches to 4 feet. Many are surrounded by a thin shell of mud-
stone or by masses of epidote and in some places the greenstone pillows
occur in a matrix of brecciated greenstone and red jasper. These meta-
volcanic rocks are part of the Upper Jurassic Amador group and the
mine workings are near the crest of a large northwest-trending anticline
(Taliaferro, 1943, p. 125).
The La Victoria ore zone, exposed for 125 feet along the main level,
is found along the main shear zone of a system which strikes N. 50° "W.
and dips 10° -45° northeast. A second mineralized shear zone near the
Cavagnaro shaft trends N. 45° W. and dips 30°-60° northeast. The
two mineralized zones are truncated by the Poupion shear zone which
strikes N. 60°-80° W. and dips 65°-87° north. This zone is not min-
eralized. In the La Victoria ore zone the copper-bearing part of the
shoot is restricted to the part of the shear zone that strikes N. 15° W.
The more west-trending part of the zone is principally quartz-pyrite
rock with very little copper. Ore occurs in pods a few inches to 15 feet
long and from 1 to 3.2 feet wide, although masses of oxidized ore re-
moved during the early history of the mine may have been larger.
Primary ore consists of fine-grained chalcopyrite, pyrite and quartz.
Secondary minerals are chiefly azurite, malachite and chalcocite.
Browne (1868, p. 213) mentions a considerable quantity of black oxide
in ore mined in the 1860 's. The average copper content of pillar sam-
ples in the upper workings of the mine is 5.3 percent and 4.1 percent
on the bottom level. The ore was partly oxidized for the full depth
mined and completely oxidized for a depth of 30 feet below the outcrop
of the mineralized zone. Copper had been almost completely leached
from the uppermost 20 feet of vein matter.
According to Cox and Wyant (1948, p. 131) the enriched 5 percent
ore of the mine is nearly exhausted, but a small amount remains in
pillars above the bottom level. A 2-foot-wide ore shoot in the north-
trending part of the La Victoria ore zone continues below the present
mine workings and may have a strike length of 110 feet. The average
grade of primary ore on the bottom level, which runs 4 percent copper,
2 percent zinc and less than 0.1 ounce of gold per ton, may represent
the grade of ore to be expected below. The only other zone believed
to carry copper ore is the one just east of the Cavagnaro shaft.
Pocahontas Mine. Location: NW i sec. 12, T. 7 S., R. 17 E., M.D.,
one mile north of White Rock School by good dirt road. Ownership:
Estate of Eben N. Briggs, c/o L. M. Olds, 57 Post Street, Room 402,
San Francisco, California.
The Pocahontas mine has been the most productive copper mine in
Mariposa County, having yielded more than 700,000 pounds of copper
as well as considerable gold and silver. The gross amount realized from
the mine has been well over $100,000. The Pocahontas deposits were
discovered in the early 1860s but apparently were not extensively
mined until the early 1900s. The property was owned in 1903 by J. E.
Waller of LeGrand, and was under lease to C. and S. Wilcox of White
Rock. These lessees mined and shipped over $30,000 worth of copper
68 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
ore in a three-year period (Aubury, 1905, p. 210). The mine then
passed into the ownership of Mrs. Abbie Waller and was under lease
for a short time by William Mcintosh and W. M. Darling of San Fran-
cisco. By June 1907 the mine had been taken over by the Pocahontas
Copper Mining Company, was operated under the direction of J. B.
Roberts for a short time, and then under direction of David Ross. By
August 1907, the shaft had been sunk to a depth of 145 feet, plans had
been made to sink 500 feet deeper and a smelter was planned (Eng.
and Min. Jour., vol. 84, no. 12, p. 563, 1907). Late in September 1907
the property was leased to the Michigan Steamship Company of San
Francisco (Eng. and Min. Jour., vol. 84, no. 19, p. 896, 1907) but this
lease apparently was short lived. The Pocahontas Copper Mining Com-
pany or its lessees worked the mine during World War I. According to
U. S. Bureau of Mines records, the Pocahontas mine produced 6,985
tons of ore from 1902 to 1913, inclusive, that yielded 621,273 pounds
of copper, 383.92 ounces of gold, and 12,618 ounces of silver. A small
amount of ore was shipped by lessees in 1914 and in 1916 1,200 tons
of ore was shipped that yielded 63,220 pounds of copper. The mine has
been idle since World War I but is still owned by heirs of officers in the
Pocahontas Company.
The Pocahontas mine workings are driven in contact-altered rocks
of the lower (?) member of the Upper Jurassic Mariposa group.
These wall rocks consist principally of quartz-biotite and quartz-
biotite-andalusite schist and quartz-biotite hornfels derived from tuf-
faceous sediments. Along the mineralized zone a sheet of hornblende-
rich granitic rock has been intruded parallel to the schistosity and
other thin sheets of biotite quartz diorite have penetrated the schists
near the mine openings. A stock of biotite quartz diorite crops out less
than 400 feet southeast of the main shaft. The hornblende-rich dike
has been hydrothermally altered and mineralized and the original
nature of the rock is, in many places, unrecognizable (Forstner, 1908,
p. 748). Some hornblendite is on the dump but this rock does not crop
out conspicuously because of masking limonite-quartz gossan.
The copper mineralization is concentrated in a shear zone which
strikes N. 35° -45° W. and dips northeast at angles between 65° and
80°. The primary sulfide ore occurs in lenticular masses in a gangue of
brecciated wall rock and introduced quartz. One of the sulfide ore
shoots mined in the early 1900 's was 50 feet long, 4 feet wide and more
than 100 feet deep (Aubury, 1905, p. 210). Much of the primary ore
is a dark bluish, massive, fine-grained rock composed predominantly
of chalcopyrite, pyrite, sphalerite and pyrrhotite. According to Aubury
(1905, p. 210) this type of ore ran 6 to 12 percent copper and $2.50
per ton in gold (at the 1902 price). The ore-bearing zone has been
oxidized and secondarily enriched to a depth of about 100 feet but most
of this ore along the main ore zone has been already mined. Much of
this oxidized ore, consisting principally of malachite, chrysocolla and
azurite, ran from 30 to 35 percent copper. Minable oxidized ore reached
a width of 20 feet (Forstner, 1908, p. 747-748) in some shoots.
Workings (September 1954) consist of 7 shafts from 15 to 75 feet
deep and a tunnel driven northwest, opening four or five hundred feet
southeast of the main shaft. Most of the shafts are inclined steeply
east and follow the ore zone. The main shaft is surmounted bv a wooden

headframe and ore bin, both in poor condition. According to Lowell
(1916, p. 573) this shaft was 300 feet deep in 1913 and there was a
total of 900 feet of drifts from the various shafts. Julihn and Horton
(1940, p. 166) place the depth of the main shaft at only 200 feet. In
1954 the shaft was caved at a depth of 75 feet. The tunnel, described
as 200 feet long in 1913 (Lowell, 1916, p. 573) is driven N. 33° W. on
mineralized material. It is caved a few feet from the portal, and is
inaccessible.
Estimation of reserves is not possible because the condition of the
workings makes entry unfeasible. There are numerous gossan outcrop-
pings which do not appear to have been explored and several shear
zones parallel to the principal ore zone have not been thoroughly
prospected. Showings of copper minerals may be seen over a width of
more than 1000 feet. A number of small masses of high-grade copper
ore were found south of the present workings at the contact of the
metasedimentary series and coarse-grained quartz diorite (Forstner,
1908, pp. 747-748). None of the old accounts indicates that there is a
lowering in the grade of the sulfide ore at depth.

most mines, gold mining has always been vital to the economy of Mari-
posa County. The total gold production of Mariposa County through
1954, which amounts to about $48,000,000, is only part of the wealth
brought into the county through businesses connected directly or indi-
rectly with mining. A variety of factors, particularly a rise in the price
of gold, could quickly change the economic structure of gold mining
and result in rejuvenation of the gold mining industry. A majority
of the mines has not been exhausted of ore and their reactivation
awaits some significant change in the economics of precious metal
mining.
Placer-gold was discovered in Mariposa County about 1848, although
precise details are lacking. Among the earliest placer miners wrere
Mexicans or Californians of Spanish descent. Much of the geographic
nomenclature still in use in western Mariposa County is drawn from
the Spanish place names such as Mariposa (butterfly), Agua Fria
(cold water) and Hornitos (little ovens). Discovery of lode-gold is
commonly credited to Kit Carson and two associates at the Mariposa
mine in 1849, but again the more secretive Mexicans may already have
been working their arrastras in the Hornitos district. John C. Fre-
mont's Las Mariposas Spanish land grant was interpreted as including
the southern end of the soon-to-be-famous Mother Lode, and after
lengthy litigation a very large area was set aside for private adminis-
tration and not developed in the same fashion as claims located on
public lands. As the Las Mariposas Grant mines were not located and
surveyed according to early public land survey practice, land plats
Nos. 1 and 2] mines and mineral deposits, mariposa county 71
within the grant to this day are difficult to locate with respect to survey
lines outside of the grant.
In addition to Las Mariposas grant, a large block of land north
of the Merced River was held under single management by the Cook
Estate and these two great properties greatly affected the course of
gold mining in Mariposa County. Under these large enterprises there
were notable periods of efficient and profitable management of the
mines. At other times the mines suffered from mismanagement and lack
of incentive toward vigorous development. It is a moot question whether
the mines of the two properties as a whole would have proven more
productive in the course of normal development under public land
regulations than they have under the collective management of the two
large interests.
As in other Sierran foothill counties, the lode-gold mines of Mari-
posa County have been conveniently grouped, for the sake of discussion,
into the Mother Lode, East Belt and West Belt groups. The Mother
Lode is a system of mesothermal quartz veins occupying a major thrust-
fault zone. It is not a single great, continuous vein but rather is a series
of discontinuous veins which in places are parallel to subparallel, en
echelon, and in other places anastomosing or braided. In general, the
veins of the Mother Lode have a northwest strike and a steep northeast
dip but in the Bear Valley-Bagby segment of the lode the strike swings
more to the north. In the vicinity of Coulterville the Mother Lode con-
sists of two well defined, roughly parallel veins the more easterly of
which diverges south of the Virginia Belmont mine and veers more to
the southeast. Along the main length of this branch are the Louisa and
Mary Harrison group of mines and the Virginia-Belmont group. A
series of pocket mines is located astride the southeast-veering segment,
called the Flyaway group. The more westerly vein in the Coulterville
area, considered by some to be the main Mother Lode, is almost con-
tinuously traceable from the Malvina group south through the Midas
and Adelaide mines and southeast toward the Merced River at Bagby.
In addition to the predominating northwest-trending veins of the
Mother Lode system there are structurally related minor cutter veins
that join the northwest examples roughly at right angles. In some of
the mines of the Penon Blanco segment of the Mother Lode the richest
ore occurred in the cutter veins rather than in the larger veins of
northwest trend. In the vicinity of Mormon Bar, a few miles south of
Mariposa, the Mother Lode terminates in granitic rocks.
The West Belt is made up arbitrarily of all mines located west of the
Mother Lode system and the East Belt of all mines located east of it.
There is no well-defined, parallel gold-quartz vein system either east or
west of the Mother Lode in Mariposa County that has any comparable
magnitude, although a number of East and West veins do roughly
parallel the Mother Lode. Within the East and West Belts are veins
of almost all attitudes, and east-northeast strikes prevail in some parts
of the county instead of the more usual north to northwest trends
found in the Mother Lode system.
Gold in paying concentrations is generally found localized in shoots
adjacent to a large volume of valueless vein matter. The conspicuous
masses of milky quartz cropping out along the Penon Blanco are largely
devoid of gold and paying ore is found principally along the upper
72 CALIFORNIA JOURNAL OP MINES AND GEOLOGY [Vol. 53
(hanging) wall or lower (foot) wall of the vein. In other places the
high-grade ore is found in the middle of the vein flanked on both sides
by barren vein matter. Masses of ore (shoots) commonly have one long
and two short dimensions and in Mother Lode veins the longest dimen-
sion commonly dips downward in the vein at a steep angle. For ex-
ample, most of the ore taken from the Princeton mine was from a
single, almost vertical, chimney-like shoot more than 600 feet deep
(Knopf, 1929, p. 84). Knopf (ibid. p. 26) states that the average slope
length of most ore shoots on the Mother Lode as measured along the
strike of the vein is 200 to 300 feet, although the shoots tend to be much
more persistent in depth. Ore commonly occurs where veins bulge,
where there is an abrupt change in strike or dip of the vein, or where
a cutter vein joins the main vein. Conditions of ore formation in one
mine do not, however, necessarily persist in other mines of a district
or even in adjacent mines.
Lode Mines
A-J (Burkhart) Mine. Location: Sec. 26, T. 4 S., R. 16 E., M.D.,
near the head of Burns Creek 3 J airline miles west of Bear Valley.
Owner : B. F. and Ruth L. Burkhart, Bear Valley, California own one
unpatented claim.
The A-J mine was first opened in the 1920s at which time a 220-foot
adit was driven. The property had been worked intermittently up to
the fall of 1954, the most recent operation by the Richardson Brothers
of Bear Valley terminated in May 1954. Recent production has been
small with ore averaging about 0.4 oz. of gold per ton.
Gold occurs free and with sulfides in a quartz vein 1 foot to 4 feet
wide, the vein striking north and dipping steeply east. The wall rock is
meta-augite andesite (greenstone) of Upper Jurassic age belonging to
the Pefion Blanco member of the Amador group (see Taliaferro, 1943,
pp. 282-284). A 150-foot shaft and three levels 35 feet apart are the
principal active workings. Vein minerals include pyrite, chalcopyrite
and free gold with minor amounts of green copper carbonates. Milling
is done in a small Gibson mill which remains on the property.
Adelaide and Anderson Mines. Location : NE J sec. 22, NWJ sec. 23,
T. 3 S., R. 16 E., M.D., in the southern end of the Big Bend Mountains
4 miles south of Coulterville and 1 mile north of the Merced River.
Ownership : Alfred W. Stickney, 435 Hillcrest Road, San Mateo, Cali-
fornia owns two patented claims, the Adelaide and Anderson, and two
unpatented millsites on the Merced River.
The Adelaide and Anderson claims were located during the late
1860s or early 1870s. By 1874 the claims had become part of a group
that included the Midas, Crown Lead and Crown Peak claims. These
were surveyed for patent purposes in 1874 and patent was established
by Fred and Mary MacCrellish about 1875. The Adelaide and Ander-
son claims were worked by the MacCrellishes in the late 1870s and
early 1880s first by open cuts and then underground. During this
period most of the workings were driven and most of the stoping on
the main ore shoot in the Adelaide mine was accomplished. A mine acci-
dent in 1885 resulted in the death of Fred MacCrellish and injury to
his wife, and mining was discontinued. By 1895 ownership of the mines
had passed to Robert E. McSherry of Coulterville and the Mary C.
Nos. 1 and 2] mines and mineral deposits, mariposa county 73
MacCrellish estate. By 1914 the properties were under management
of W. P. Edwards of Alameda. No material amount of work was done
on either claim between 1885 and 1933. In 1934 leasers drove 440 feet
of tunnels and drifts about 2000 feet south of the main workings on the
Adelaide claim. A satisfactory ore body was not encountered there and
the mines again became idle. In 1943 the properties were acquired by
the present owner and some cleaning out and sampling was done on the
Adelaide claim, particularly, near the main ore shoot. Since that time
both claims have been idle.
The quartz vein at the Adelaide mine, part of the Mother Lode
system, strikes N. 27° W. to N. 35° W. and dips 50° northeast (aver-
age). Its course is slightly sinuous and vein matter thickens and thins
between the limits of 6 and 10 feet. The principal known ore shoot is
25 feet wide, measured along the strike of the vein, and has been
stoped to a depth of 215 feet as measured in the plane of the vein. The
shoot pitches northwest at about 68°. The vein has developed in a
fissure that follows the east contact between a narrow mass of ser-
pentine, on the footwall side, and a belt of black slate of the Mariposa
formation on the northeast or hanging wall side. Both slate and ser-
pentine are believed to be of Upper Jurassic age. The slate occupies a
faulted synclinal trough between a large serpentine mass on the east
and a thick section of meta-augite andesite greenstone of the Upper
Jurassic Penon Blanco formation (Taliaferro, 1943, pp. 282-284) on the
west. The narrow mass of serpentine which forms the footwall of the
main Adelaide vein has been intruded between much broader masses
of slate and greenstone. Farther north the greenstone is in direct con-
tact with slate.
In addition to the massive milky quartz, so prominently exposed on
the surface of the Adelaide claim, vein matter in numerous places
consists of a banded or ribbon-structure of alternating quartz and slate
or quartz and talcose serpentine layers. In other places vein matter
consists predominantly of quartz, ankerite and mariposite, both massive
and banded. Pyrite heavily impregnates the vein material at numerous
points. Gold occurs partly in the free state and partly in intimate mix-
ture with pyrite. Associated ore minerals are galena and chalcopyrite.
Presence of tellurides mentioned in an old account by Fairbanks (1890,
p. 57) has not been confirmed. According to Fairbanks the best ore is
found in a 2-foot-thick tabular mass on the footwall side of the vein.
The most important workings are at the north end of the claim in
the vicinity of the principal ore shoot. These originally consisted of
the 100-foot-deep Cobb inclined shaft; the 350-foot-long Cobb tunnel,
driven northwest on the vein and intersecting the Cobb shaft 230 feet
from the tunnel portal; a winze or interior shaft sunk about 100 feet
from the tunnel portal; and two shallow inclined shafts with minor
drifts. One of the two auxiliary shafts is 200 feet north of and the
other 140 feet south of the Cobb shaft.
About 1,000 feet south of the Cobb tunnel portal is the entrance to
the Boarding House tunnel driven south to southeast along a sec-
ondary vein and having three segments 60, 150 and 30 feet long, re-
spectively. About 210 feet from the portal of this tunnel is a winze 60
feet deep sunk on the vein. This is believed to have been connected with
a lower west-trending tunnel, now inaccessible. Two shafts are located
74 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
south of the Boarding House tunnel, one 100 feet deep and the other
60 feet, deep.
About 2,000 feet southeast of the Cobb shaft is a 290-foot crosscut
tunnel and connecting 150-foot drift driven west and northwest. The
drift appears to be on a different vein than the main workings, a nar-
rower one about 2 feet wide. These workings are largely southeast of
the Adelaide claim boundaries.
In addition to the aforementioned workings there are several super-
ficial open cuts, pits and short tunnels. The total length of development
workings is more than 2,500 feet. The stoped part of the ore shoot
totals roughly 130,000 cubic feet.
Little is known concerning the tenor of the ore in the Adelaide mine
and the present owner was unable to reach the ground below the caved
stopes in the vicinity of the main ore shoot. Samples taken by the
owner at various places in the workings assayed from 1 dollar to 7
dollars per ton at the present price of gold. Future development work
should explore the ground below the stoped area by cleaning out and
deepening the winze from the Cobb tunnel.
The Anderson mine is a quarter of a mile east and slightly south of the
Adelaide mine. The main vein strikes about N. 15° W., dips northeast at
an average of 42° (Turner and Ransome, 1897, economic map), and
averages 4 to 12 feet wide. Little or no work has been done on it since
1885. The workings, all caved and inaccessible, consisted of two in-
clined shafts, three tunnels and two short open cuts. The amount of
stoping done is not known. Wall rocks are slate but there is a small
intrusion of granodiorite on the southwestern part of the claim. The
more northerly shaft, 75 feet deep, is sunk at the geographic center of
the claim and once connected with a 175-foot tunnel to the surface
bearing N. 75° E. The other shaft was originally 120 feet deep and was
connected to the surface by a 350-foot-long tunnel trending N. 60° W.
A third tunnel 120 feet long was driven N. 15° W. along the vein.
There is no record of production for the Anderson mine and no data as
to the tenor of the ore.
Annabelle Prospect. Location: Sec. 19, T. 35, R. 17 E., M.D., 4 air-
line miles southeast of Coulterville and 3J airline miles northwest of
Bagby on the northwest side of Scotch Gulch at its intersection with
Highway 49. Ownership : Mr. and Mrs. Sherman S. Pickard and Bryan
A. Miller, P. O. Box 36, Coulterville, California, own one unpatented
claim.
The Annabelle prospect is a small pocket mine opened in 1952. The
mine workings lie along a line of small, discontinuous quartz veins
which strike slightly east of north and dip 40° east. The vein system
lies at or close to the contact of serpentinized peridotite lying to the
west, and slightly older metavolcanic greenstones lying to the east. A
quartz diorite dike intruded along serpentine greenstone contact forms
the footwall of the veins and the hanging wall is meta-andesite green-
stone. Next to the quartz veins is a narrow zone of fractured greenstone
and talc schist commonly cut by quartz stringers. The fractured green-
stone and in some places the adjacent greenstone wallrock is mineral-
ized and carries pyrite and auriferous pyrite. The quartz veins and
Nos. 1 and 2] mines and mineral deposits, mariposa county

stringers carry free-milling gold, often in pockets. Serpentinized gabbro
forms the hillslope to the west across Highway 49.
Workings consist of a shallow shaft inclined 40° east with a 16-foot
drift driven northeast along the vein from the bottom of a short cross-
cut. About 30 feet northwest of the shaft a horizontal tunnel has been
driven northwest.
Some good specimen material has recently been obtained from this
mine and there has been a small but fairly steady production since
1952. Work is done entirely by hand methods and there is no mill con-
nected with the property.
Argo (Pioneer) Mine. Location: Sees. 15, 16, T. 2 S., K. 17 E.,
M.D., 7 airline miles northeast of Coulterville in the Greeley Hill dis-
trict. Accessible by three-quarters of a mile of dirt road north from
the Coulterville-Kinsley road. Ownership : Walter D. McLean, Coulter-
ville, California, owns two unpatented claims, the Argo and the Pioneer.
The Argo property has been owned by the McLean family since the
early 1920s. It was leased from Walter McLean in 1931 by C. A.
Gillis of Tuttletown and J. H. Hollbrook, Jr., of San Francisco. U. S.
Bureau of Mines records show an intermittent production from the
mine between 1923 and 1935. During the winter of 1937 two men re-
covered $76.00 worth of gold in 3 days from soil mantle in a small
gulch south of the Argo shaft (Julihn and Horton, 1940, p. 135).
Milling of 24 tons of dump material in 1949 yielded 18 oz. of gold

or an average of $26.25 per ton. Except for assessment work the claims
have been idle since 1949.
The Argo vein occurs in a shear zone striking N. 10° W. to N. 15° W.
and dipping 50°-55° E. It has an average width of 2 feet and a maxi-
mum width of 5 feet. In some places brecciated wall rocks have received
a stockwork of quartz stringers. Wall rocks are blue-black quartz-
biotite hornf els, black quartzite and a medium-grained, altered intrusive
rock, either diabase or diorite. According to the owner the high-grade
ore occurs in small shoots and pockets in which specimen gold is asso-
ciated with quartz and pyrite. Two ore shoots were discovered at or
near the surface and about 100 feet apart (Julihn and Horton, 1940,
p. 135). One about 40 feet long and 75 feet deep yielded 150 tons
of ore from which 120 oz. of gold was extracted. The second shoot has
been worked from the surface to a depth of 200 feet and has yielded
408 oz. of gold from 800 tons of ore or an average of slightly better
than 0.5 oz. per ton ($17.85 per ton). This ore shoot was 30 feet long
on the 50-foot level, but lengthened to 120 on the 100-foot level and
tapered to 40 feet long on the 200-foot level. Ore remaining in the
shoot on the 200-foot level is said to average about 1 oz. of gold per
ton (Julihn and Horton, 1940, p. 135) — calculated to the present price
of gold — from slightly more than 1000 tons of ore. The total recorded
production of the mine is about $18,500.
Workings consist of several open cuts and a 200-foot inclined shaft
with several levels and stopes. Equipment on the property includes a
4-inch jaw crusher, 3 stamps, amalgamating plates, 2 concentrating
tables, a dismantled steam hoist and skip. The wooden headframe and
shaft are in a fair state of repair but the mine is partly flooded. There
are several serviceable buildings as well as the mill. Sufficient water
for milling purposes is obtained from the mine.
Badger (Prescott) Mine. Location: Sec. 2, T. 5 S., R. 16 E., M.D.,
on the Eldorado Creek road between the Mount Gaines and Number
Nine mines or about 6| miles by road from Hornitos. Adjoins the
Number Five mine on the north. Ownership : Mrs. Charles B. Cavag-
naro, Hornitos, California owns the Prescott lode claim and mill site.
The Badger mine was discovered in the 1850s and is reported to
have yielded $80,000 from surface workings during the early days of
its history. Most of the later activity at the mine has not been recorded,
but ownership has been in the Cavagnaro family for more than 30
years. The last work done on the mine was by C. S. Shafer and son of
Hornitos in 1934. A small production was recorded at that time.
The Prescott vein is a rather sinuous, north-trending vein 1 foot
to 3 feet wide dipping 30-45° east. Judging from the numerous shallow
pits and other surface workings there must be several other parallel
stringers or small blanket veins. Near the end of the line of main
workings on the Prescott vein is a west-striking, nearly vertical cutter
vein which has been stoped for a distance of over 500 feet. It is 1 foot
to 3 feet wide and consists principally of milky quartz with abundant
pyrite and some chalcopyrite. The quartz contains many vugs lined
with crystals. The Prescott vein is of similar character. The authors
were unable to determine whether the west-trending line of workings
is part of the Badger mine or not. Wall rocks are blue-black, massive,
Nos. 1 and 2] mines and mineral deposits, mariposa county 77
spotted slate, schistose greenstone, black hornblende schist and horn-
felsic slate, probably of Upper Jurassic age.
The Prescott vein is developed by several west and northwest-trend-
ing crosscut adits driven from the east slope of the ridge and a few
short ones driven from the west side of the ridge. There are extensive
drifts and stopes connecting with these workings and the whole hillside
is covered with pits. Several of the crosscuts are accessible but in need
of cleaning out, and workings below the lower adit levels are flooded
(January, 1956).
Bandarita ( Bandar etta, Eclipse, Goodwin). Location: NWJ, sec.
7, T. 3 S., R. 18 E., M.D., on the North Fork of the Merced River at
its confluence with Gentry Gulch 11 airline miles east of Coulterville.
Ownership : W. Lee Brown, c/o W. J. Beatty, Coulterville, California,
owns 4 patented claims, the Bandarita Nos. 1 and 2, Little Fort Knox
and Fort Knox No. 2. Nelson M. Leoni, c/o Dolores Pharmacy, Carmel-
by-the-Sea, California, owns three patented claims, the Kinsley Nos. 1,
2, 3. In September 1954, the mine was accessible only by trail because of
a washout on the Gentry Gulch road.
The Bandarita mine was discovered in 1856 (Browne, 68, p. 33) by
Thomas E. Palmer and profitably worked almost continuously for more
than 30 years. During the first 20 years the Goodwin Brothers and
Peter Wynant were the principal operators. In 1873 operation of the
mine was taken over from the Goodwins and Wynant by a San Fran-
cisco company under management of a man named Hanagan (Eng.
and Min. Jour., 1873, vol. 16, no. 26, p. 412). By 1874 management had
reverted to the Goodwin Brothers (Min. Sci. Press, 1874, vol. 29, no. 9,
p. 133) who in a single mill cleanup took 25 pounds of gold from 100
tons of ore! By August 1876 management of the mine had passed to
Levi Keyes, presumably still under ownership of the Goodwin Brothers
(Min. Sci. Press, 1876, vol. 33, no. 10, p. 157). More than $160,000 was
spent for mine machinery between 1872 and 1876 entirely from pro-
ceeds of the mining operations. About Jan. 17, 1880 a new 10-stamp mill
run by water power was put into operation (Min. Sci. Press, 1880,
vol. 40, no. 3, p. 37). Ownership passed to P. P. Mast of Coulterville
about this time and C. L. Mast took over as superintendent. The Masts
began to drive a tunnel from the level of the mill to crosscut the main
vein 1200 feet from the surface outcrop (as measured along the vein).
This ultimately reached a length of 1364 feet and encountered ore aver-
aging $25.00 per ton. According to Julihn and Horton (1940, p. 141),
the period 1881 to 1887 was the most productive in the mine's history.
By 1889 the most of the ore above the lowest tunnel level had been
stoped out and the mine became idle (Eng. and Min. Jour., vol. 42,
no. 22, p. 407). Intermittent work was done from 1890 to 1898. Early
in 1898 Lafayette Gold Mining Company of San Francisco leased the
mine with the idea of cleaning out the lowest tunnel and sinking lower
from the tunnel level. (Eng. and Min. Jour., vol. 65, no. 8, p. 229.)
Little is known of the results of this operation, but by 1904 ownership
had passed to Rodgers and Loomis of Springfield, Ohio. There is no
record of work of any extent on the mine from 1904 to 1928 when own-
ership passed into the hands of Gentry Gulch Consolidated Mines Com-
pany of San Francisco (Laizure, 1928, p. 89). This operation was
78 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
apparently short-lived and there is no known record of production from
the Bandarita mine at that time. About 1937 the mine was leased from
the owners, Nelson M. Leoni and J. E. Brown, by four partners, William
Beatty, W. M. Boyer, Carl Crouse and G. A. Ogden (Julihn and Hor-
ton, 1940, p. 141) who operated the mine until 1943. Since 1943 the
mine has been idle.
The Bandarita mine is credited with a total production of $1,520,000
much of which was mined between 1881 and 1887, according to Julihn
and Horton. During the last period of activity, from 1937 to 1943, ap-
proximately $40,000 in gold and silver was obtained from 7362 tons of
ore (U. S. Bur. of Mines records), the tenor of the ore being $5.42 per
ton or considerably lower than the ore milled in the 1880s.
The principal vein at the Bandarita mine strikes N. 84° W. and dips
about 47° S. Its width varies from 2 to 10 feet. Wall rocks are slate,
quartz-biotite hornfels and granitic dike rocks. The metasedimentary
series has been assigned to the Paleozoic Calaveras formation (group)
by Turner and Ransome (1897).
In addition to native gold the ore contains pyrite, galena, sphalerite
and tetrahedrite, the best ore containing considerable tetrahedrite. Pres-
ence of tellurides, mentioned by S. Rudolph (Min. and Sci. Press, 1880,
vol. 40, no. 11, p. 162) has not been confirmed by later writers. Julihn
and Horton (1940, p. 141) visited the property in 1938 and the follow-
ing data is drawn largely from their report. There are four granodiorite
dikes which strike roughly north and intersect the vein approximately
at right angles to it. The vein has been faulted at these intersections with
throws of from 1 foot to 42 feet.
The mine is developed by a 1364-foot crosscut adit, the portal of which
is 50 feet above river level, and by six adits driven along the strike of
the vein, two on the east side of the hill and four on the west slope of
the hill. The longest of these adits, 800 feet in length, is driven into the
east slope and taps three ore shoots stoped from the surface to various
depths between 75 and 650 feet. The crosscut adit taps the vein about
850 feet vertically from the surface or 1200 feet as measured along
the vein.
In 1938, lessees stated that there was 275,000 tons of gob (broken ore)
in the old stopes of the mine that would pay to mill at costs prevailing
at the time and at the prevailing price of gold. The lessees were, how-
ever, mining unbroken ore from the Goodman (Goodwin (?)) shoot
which was reputed to average 0.57 oz. of gold per ton.
Black Hill (Pumpkin) Mine. Location ■ E-J, sec. 33, T. 2 S., R. 16 E.,
M.D., half a mile northwest of Coulterville. Adjoins the Margaret claim
on the north. Ownership : Louise A. Boyd, 265 California St., San Fran-
cisco 11, California owns 40 acres of patented land.
The Black Hill or Pumpkin mine is the most northerly mine in the
Mary Harrison group, all of which are aligned on a branch of the
Mother Lode vein system commonly called the east branch. The east
branch is roughly en echelon to the west branch on which are aligned
the Malvina group of mines. The two branches are approximately 4700
feet apart.
The mine probably was discovered and first worked at about the same
time as the Mary Harrison, about 1867. There is little record of activity
before the 1890s although considerable development work must have
Nos. 1 and 2] mines and mineral deposits, mariposa county 79
been done. There was a 600-foot tunnel on the property as early as 1895
(Storms, 1896, p. 216) at which time the owners were Clark and McLay-
mont of Coulterville. By 1900 ownership had passed to John Boyd and
the mine had been reopened under the management of J. J. Dolan. A
new shaft was sunk to a depth of about 100 feet (Eng. and Min. Jour.,
vol. 70, no. 22, p. 647) and some rich ore was discovered. Very little
work has been done on the property since 1902.
At the Black Hill mine the east branch of the Mother Lode strikes
N. 35° W. and dips about 45° northeast. The vein is close to the contact
between a serpentine intrusion and slate of the Mariposa formation, but
at the surface the wall rocks are entirely serpentine. Vein matter is
chiefly quartz-ankerite-mariposite rock and the vein is more than 20
feet wide. Considerable low-grade ore is found as pyritic impregations
in serpentine wall rock adjacent to the vein.
Workings consist of a main inclined shaft, surmounted by a wooden
headframe and ore bin, two tunnels driven northeast and several auxil-
iary shafts and stopes. The main shaft is watered and partly caved and
the other workings are all caved and inaccessible. There is a tool shed
in good condition on the property (September 1954) but no mining or
hoisting machinery.
Bondurant (Hathaway-Bondurant). Location: Sec. 25, T. 2 S., R.
17 E., M.D., 12 miles east of Coulterville near the North Fork of the
Merced River. Ownership : A. E. Adams, et al., 367 Maude Ave., San
Leandro, California own one patented claim.
The Bondurant mine is the second oldest patented mine in the county,
patent having been issued in 1856 (Julihn and Horton, 1940, p. 138).
It was mined by hand methods and ore was treated in arrastras during
the early years of operation, and one of the early owners was Judge
Bondurant for whom the mine is named. By the late 1870s ownership
had passed into the hands of Joshua Hendy of San Francisco who in
1879 sold the Bondurant and Martin-Walling mines to an eastern com-
pany for $80,000 (Min. and Sci. Press, vol. 39, no. 1, p. 5).* At that
time a 10-stamp mill was operating 24 hours a day on $30.00 per ton
ore. After a period of inactivity in the early 1880s the Hathaway-
Bondurant Gold Mining Company was organized in 1887 with a cap-
italization of $1,000,000 (Min. and Sci. Press, vol. 44, no. 10, p. 173)
and the mine was placed under the management of T. T. Hathaway.
This operation ceased in 1891. After 5 years of intermittent activity
the mine was unwatered and sampled by the Bruner Brothers of St.
Louis, Missouri, Charles Bruner, superintendent. About 1902 the mine
was taken over by the Boston and Mariposa Mining Company, Fred
Whitman, superintendent, but this operation was also short-lived. In
July 1911 under the management of George H. Gerkin, specimen ore
was discovered on the 300-level and another high-grade shoot was dis-
covered soon thereafter between the 150 and 200 levels (Min. and Sci.
Press, vol. 103, no. 3, p. 90, 148). In 1913 ownership passed to the
Bondurant Gold Mining Company, A. L. Adams, Bridgeport, Connec-
ticut, the principal owner. A crosscut adit started by previous owners
near the level of the Merced River, calculated to strike the vein at a
distance of about 1400 feet from the portal, apparently was lengthened
* Walter McLean, Coulterville, California, suggests that this transaction probably in-
volved the Bandarita mine rather than the Bondurant.
80 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
under this management. The adit apparently was only driven 945 feet
(Lowell, 1916, p. 577). In 1916 the mine was sold by Adams to George
R. Stone, Bridgeport, Conn., but little or no work was done under this
ownership (Min. and Sci. Press, vol. 102, no. 18, p. 106). From 1926 to
1928 or 1929 the mine was operated by the Bondurant Mining Trust of
Modesto, a partnership of Walter and Arthur Ritz (Laizure, 1928, p.
81). The Ritz management extended the crosscut adit started by the
Adams operation to 1400 feet. From about 1929 to October 12, 1940 the
Bondurant Mining and Milling Company of San Francisco operated the
property and it was during this period that the largest production was
recorded. The known production up to October 12, 1940 is about $292,-
000. From that date to October 15, 1942, when closed by War Pro-
duction Board order, the Boston-California Mining Company mined
between 12,000 and 14,000 tons of ore which yielded approximately
$98,000. Consequently the total known production of the mine is $390,-
000. Between 1911 and 1915 approximately 746 tons of ore mined
yielded 431.95 oz. of gold, 259 oz. of silver and 3672 pounds of copper.
From 1931 to 1940 a total of 16,596 tons of ore mined yielded 7879.92
oz. of gold and 5176 oz. of silver.
There are three major, roughly parallel veins on or closely adjacent
to the Bondurant property known as the Bondurant, Reynolds, and
Louisiana. No material amount of work has so far been done on the
Reynolds or Louisiana veins on the Bondurant property. The Bondu-
rant vein strikes generally N. 65° W. and dips 35° to 45° E. at the
surface. It is about 3 feet wide where it crops out at the surface but
averages 4 feet wide at depth (McLean, W. D., personal communica-
tion, 1956). Vein matter now exposed at the collar of the shaft is chiefly
hydrothermally altered, micaceous dike-rock, but most of the gold
occurs in quartz with pyrite, chalcopyrite, sphalerite and galena. Ac-
cording to the recorded production figures ore has average 0.48 oz. of
gold and 0.31 oz. of silver per ton. Much of the dump material is pyrite-
impregnated slate and other wall rock which must carry some gold.
Wall rocks enclosing the Bondurant vein are crumpled slates, slaty
mica schists and coarser-grained gneisses, presumably part of the Paleo-
zoic series generally known as the Calaveras group. The precise char-
acter of the altered dike-rock associated with quartz vein-matter cannot
be determined from hand specimens, but it probably is a fine-grained,
biotite-rich granodiorite.
In August, 1954, the principal working at the Bondurant mine was
a 10xl2-foot shaft inclined 45° toward the northeast. This was filled
with debris below an inclined depth of about 100 feet. According to
Julihn and Horton, the last writers to visit the mine while it was op-
erating, the shaft was 412 feet deep and had a total of 2500 feet of
drifts on 5 levels, the 100, 150, 250, 300 and 350. In 1938 the crosscut
tunnel, begun near river level and driven 945 feet in 1913-14, had
been lengthened to 1100 feet. At that time the company planned to
continue the tunnel 600 feet farther until it intersected the vein. The
projected point of intersection is approximately 1100 feet from the
surface outcrop of the vein as measured along the dip (Julihn and
Horton, 1940, p. 138). There is no record showing whether the projected
1700-foot tunnel was ever completed or not. The mine was shut down
about 1942 bv War Production Board Order L-208 and has been in-
Nos. 1 and 2] mines and mineral deposits, mariposa county 81
active since that time. All equipment has been removed from the
property and all of the workings except the upper part of the shaft
were inaccessible at the time of the authors' visit in August 1954.
Buena Vista Group (Busch, Washington-Buena Vista). Location-
Sees. 20, 21, 28, T. 4 S, R. 18 E., M.D, in the Colorado district 5 airline
miles north and slightly west of Mariposa via State Highway 49 and
the Saxon Creek Road. Ownership : C. W. and Velma Worley, Mariposa,
California own three patented claims, the Washington, Buena Vista
and Phoenix. Once included the Talc, Lucky Lindy and Charles claims.
The Buena Vista group of mines was first opened in 1882 or 1883.
In January 1884 a 10-stamp steam mill was put into operation by the
0 'Gorman Brothers (Min. and Sci. Press, vol. 48, no. 5, p. 88). By
May 8, 1886 the main shaft had reached a depth of 100 feet with
Lorenzo Alvord in charge of operations (Mariposa Gazette, May 8,
1886). Early in 1887 the mine was leased or bonded from a Dr. Turner
to Emmanuel San Pedro who operated the property for several years.
(Min. and Sci. Press, vol. 54, no. 4, p. 56) In 1892 an 8- or 9-inch wide
ore shoot was struck in the vein at a depth of 15 feet which ran $62.00
per ton in gold and $1.67 in silver. (Eng. and Min. Jour., vol. 54, no.
17, p. 397) The mine was idle much of the time between 1893 and
1916. In 1917 it was reopened by W. M. Brice, probably under lease
from L. F. W. Busch (Castello, 1920, p. 109). About 1919, Busch sold
all of his holdings except a talc claim, the Washington claim going to
Pacific States Syndicate of Los Angeles (Castello, 1921, p. 141). None
of the claims appear to have been operated to any extent until 1927
when the Buena Vista group of claims was acquired by Consolidated
Gold Fields of Mariposa, Belle McCord Roberts of Long Beach, Pres-
ident (Laizure, 1928, p. 120). This company did considerable cleaning
out and sampling and several shoots containing milling-grade and high-
grade ore were found (Laizure, 1928, p. 120-121). This operation ap-
parently did not survive the crash of 1929 and depression of the 1930 's
and the claims have been idle during most of the period 1929-1955.
The principal vein on the Buena Vista claims is 2-7 feet wide, strikes
N. 70°-75° W. and dips steeply northeast. There is at least one parallel
stringer vein. Wall rocks are slate and metavolcanic porphyries. In
1914 the principal working was a 180-foot shaft with 140 feet of drifts,
one winze of unknown length and a 67-foot crosscut tunnel (Lowell,
1916, p. 578). According to Laizure (1928, p. 1°0) most of the workings
are on the Washington and Buena Vista claims. He mentions a tunnel
driven on a stringer vein, a crosscut opening about 200 feet from the
main shaft and drifts on the vein from the crosscut tunnel. Assays
made in 1927-28 by Techow and Davis of Sacramento varied from $6.40
to $32.96 per ton (Laizure, 1928, p. 120). The mine is idle and the
property was not visited during this investigation. The foregoing data
were abstracted from the literature and from records of the U. S. Land
Office at Sacramento.
Buffalo (San Domingo) Mine. Location: SWJ, sec. 13, T. 4 S.,
R. 18 E., M.D., about 4 airline miles north of Midpines on Trabucco
Creek. Ownership : Vernon and Clara Tharp, 1850 Central Ave., Ala-
meda, California own one claim and a mill site.
82 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
Little has been written of the early history of this mine. It was de-
scribed as an old mine in 1910 at which time a large body of milling-
grade ore had been developed under direction of R. L. Mann (Min. and
Sci. Press, vol. 101, no. 15, p. 486). The most recent period of activity
was from 1932 to 1940, mainly under the management of the Gabriel
Mining Company of Midpines. There is no machinery on the property
and the workings are covered by dense brush (September, 1954). Local
prospectors report that entry to the mine may be made through the air
shaft and that the tunnel is open for nearly 300 feet past the caved
portal. During the last period of activity, a little more than $15,200 in
gold and silver was taken from the mine from an unknown tonnage
of ore.
Rocks exposed in the vicinity of the workings are slate, greenstone
and various granitic rocks. According to Castello (1920, p. 137) early
workings explored a quartz vein 2 feet wide carrying free milling gold,
having a northwest strike and northeast dip of 50°. He described the
footwall as slate and the hanging wall as granite. Workings at that
time consisted of a 400-foot tunnel, a 180-foot air shaft and several
winzes and raises. Laizure (1935, p. 29) states that the main quartz
vein varies from a few inches to 7 feet wide with several feeder veins,
all badly fractured. Ore shoots were described as short and irregular.
According to his account the vein crops out at the surface, has a north
strike and an east dip of 26°. Workings in 1935 were reported to consist
of a 310-foot tunnel and connecting winze, reaching 400 feet below the
outcrop and with 500 feet of drifts on the vein. Also, 1000 feet of
upraises and intermediate drifts and one stope 100 x 150 feet.
Campo (Campodoniea Italian) Mine. Location : NWJ, sec. 16,
T. 5 S., R. 16 E., M.D., 1 mile east of Hornitos. Ownership: Not deter-
mined.
The Campo mine was discovered in early gold rush days and worked
in a small way with an arrastra during the 1850s and 1860s. In 1874
the lower level of the Campo mine reached 110 feet below the surface
and the shaft was 205 feet deep on a 45° incline (Min. and Sci. Press,
vol. 29, no. 4, p. 53). At that time the vein was 8 feet wide, but only
a small amount of the width constituted ore. By 1876, a 10-stamp mill
had been erected which milled 10 tons of ore in a 24-hour period, ore
running $15.00 per ton at the prevailing price of gold (Min. and Sci.
Press, vol. 33, no. 12, p. 189). Chinese labor was employed. After a
period of inactivity of unknown duration the mine was reopened in
1896 by the Campodoniea Mining Company under the direction of
James Kennedy. (Min. and Sci. Press, vol. 73, no. 11, p. 222.) Under
this management the mine yielded 387 oz. of gold from unknown ton-
nage of ore (U. S. Bureau of Mines records) but the mine was again
closed down in 1898 or 1899. During 1937-1939 the mine was operated
by a group headed by N. L. Wagner, L. G. Corwin and Claude Shafer
of Hornitos. In this period 356 tons of ore were mined which yielded
238 oz. of gold and 96 oz. of silver. In 1938, the old dump sampled $8.42
per ton (Julihn and Horton, 1940, p. 125.) The mine has not been
operated since 1940.
According to Julihn and Horton, the last writers to visit the mine
while it was operating, the quartz vein averages 4 to 5 feet wide be-
tween a schist footwall and a porphyry (greenstone) hanging wall. It
Nos. 1 and 2] mines and mineral deposits, mariposa county 83
strikes north and dips 40° to 45° east, The principal working is an
inclined shaft 230 feet deep from which a large but unknown footage
of drifts has been driven. In 1938, the shaft was being cleaned out
and retimbered, a cave-in having occurred 40 or 50 feet below the collar
of the shaft. The rocks in the vicinity of the mine are slates and schists
of the Upper Jurassic Mariposa and Amador groups of rocks.
Carson (Bouvier) Mine. Location: Sees. 3, 4, T. 4 S., R. 16 E., M.D.,
in Hunter Valley 8 airline miles north of Hornitos. Adjoins Iron Duke
mine on the south. Ownership : Not determined, probably Inez Bouvier,
et al., 1431 Moraga St., San Francisco, California.
The Carson mine consists of four adjoining unpatented claims, the
Carson, Carson No. 1, Carson No. 2 and Bouvier. The Carson claim
adjoins the Iron Duke claim on the south, the others extending south-
east in the order named. All are on a well-known bluish quartz vein,
locally called the Blue Lead, which strikes N. 30° -35° W. and dips
about 60° east. The Blue Lead is crossed nearly at right angles by
several cutter veins wherein some of the best ore is found. The Blue
Lead varies from 2 to 20 feet wide and the cutter veins from 2 to 4
feet wide. The main vein is on or close to the contact between the
Hunter Valley chert and meta-augite andesite greenstone of the Ama-
dor group. Both these units are of Upper Jurassic age. In general,
chert forms the hanging wall and greenstone the footwall. The princi-
pal working, located on the Carson claim on a cutter vein about 150 feet
east of the Blue Lead, is a 125-foot inclined shaft. There are several
other prospect pits. The mine was once equipped with a 5-stamp mill,
but this burned in 1868 (Castello, 1921, p. 108). The mine is idle and
there is no equipment on the property.
Champion I Mine. Location : Sees. 28, 33, T. 2 S., R. 16 E., M.D.,
on Blacks Creek If miles N.W. of Coulterville. Ownership : Car Da
Mining Company, a trust estate (i) and Adelaide M. Ray (J), c/o C. P.
Rose, 1259 North Fuller Ave., Hollywood, California, own 1 patented
claim consisting of 10.37 acres.
The Champion I mine is a very old property probably located in the
1850s. Little is known of the early history of the mine except that it
was known to be active in 1878. From 1903 to 1905 the mine was oper-
ated intermittently by C. E. Van Meter under the management of a
Mr. Chandler of San Francisco. The main shaft was 100 feet deep in
1904 (Min. and Sci. Press, vol. 88, no. 11, p. 184) and 200 feet deep in
1905 (Min. and Sci. Press, vol. 90, no. 12, p. 197). By 1906 ownership
of the mine was held by N. S. Ray, the Mentzer Brothers and Daniel
Warner. A strike of rich ore was reported in the mine in September
1906 (Min. and Sci. Press, vol. 82, no. 12, p. 561). In 1910 the mine
was under lease to Bagby, Wilburn and McQuinn who had an operating
mill and employed 15 men. In February 1910, a single pocket of gold
yielded $74444* (Min. and Sci. Press, vol. 89, no. 7, p. 388). In the
fall of 1910 one mill cleanup from 250 tons of ore milled yielded $14,-
800 (Min. and Sci. Press, vol. 90, no. 19, p. 926). About 1914, the
mine was leased to C. I. Mentzer, et al., of Coulterville who milled
several thousand dollars' worth of ore averaging $45 per ton. In 1917,
the Champion Mining Company of Los Angeles was permitted to issue
675,000 shares of stock to C. H. White and associates for reactivation
84 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
and redevelopment of the mine. This company constructed a 10-stamp
mill and milled a small tonnage of ore which ran about 5 oz. of gold
per ton (U. S. Bur. Mines records). By 1920, ownership of the mine
had passed to Mrs. D. Wagner, Mrs. N. C. Kay and Mrs. M. A. Mentzer
(Castello, 1921, p. 110). By 1936, ownership of the mine had passed to
the Car Da Mining Company, Frank A. Notterman of Sonora, presi-
dent and general manager. In 1938, 16 men were employed. The mine
has been idle since the period 1936-38. All equipment and buildings
have been removed from the property except a tool shed and cabin. The
workings are full of water (September, 1954).
The recorded production of the Champion I mine since 1900 is about
$146,200.00 with the total production somewhere between $150,000.00
and $200,000.00. About $67,000.00 in gold and silver was produced dur-
ing the last period of activity, 1936-1939.
The long direction of the main shaft is oriented N. 70° W. and it
dips 55° northeast. The Champion claim is also oriented about N. 70 W.
(U.S. Land Office records) and this is presumably parallel to the strike
of the vein, which does not at present crop out strongly at the surface.
Castello (1921, p. 110), Laizure (1928, p. 83) and Julihn and Horton
(1940, p. Ill) all state that the main vein strikes N. 17° E. and dips
45° SE. between slate walls, but these data are evidently in error. There
is no slate on the dumps or near the workings and no evidence that the
vein strikes northeast. Rock on the dumps is serpentine and greenstone
and there is a serpentine-greenstone contact less than 100 feet east of
the main shaft. Vein matter on the dumps consists of sulfide-impreg-
nated quartz and quartz-ankerite-mariposite rock. Also in the dumps
is a large quantity of sulfide-impregnated wall rock which probably
constitutes low-grade ore. According to Julihn and Horton the ore con-
tains free gold, pyrite, galena, tetrahedrite and sphalerite. They state
that the main shaft is 440 feet deep with levels at 140, 240, 340, and
440 feet. They also mention a 200-foot exit shaft and 2000 feet of drifts,
crosscuts and raises. In 1938 the mine made about 40,000 gallons of
water per day in summer and 60,000 gallons per day in winter (Julihn
and Horton, 1938, p. 111). A complete account of the milling practice
in 1938 is described by Julihn and Horton. The mill has been removed
from the property.
There are two shafts of unknown depth about 1,000 feet southwest of
the main shaft which apparently are on the Champion claim. The rela-
tionship of these shafts with the other workings could not be deter-
mined. One of these may be the exit shaft mentioned by Julihn and
Horton.
Champion II Mine. Location: Sec. 34, T. 3 S., R. 18 E., M.D., 1J
miles south of Colorado School and east of the Colorado-Sherlock Creek
road, or 5 airline miles northeast of Mariposa. Ownership : Belle Mc-
Cord Roberts, 2625 East Tenth St., Long Beach, California, has retained
mineral rights on one claim of about 20 acres, which is part of a parcel
of patented agricultural land.
The Champion II mine was discovered sometime before the 1880s
about the same time as many other mines in the Colorado district. In
October 1889 the mine was being operated by a partnership of James
Ridgway, Colonel Dunbar and Mr. Hay. At that time it was worked
from a 4xl0-foot nearly vertical shaft 90 feet deep with drift levels
Nos. 1 and 2] mines and mineral deposits, mariposa county 85
at 60 and 90 feet run both directions from the shaft (Min. and Sei.
Press, vol. 59, pp. 320, 450, 1889; Goodyear; 1890, p. 303). Five hun-
dred tons of ore taken out during 1889-90 was reported by Goodyear
to average about $12 per ton. Ore was crushed for a time in a steam-
powered arrastra but this proved impractical and a 5-stamp mill was
planned. Management disputes apparently resulted in termination of
this period of activity. In 1919 the mine was owned by G. E. Dunbar
of Mariposa but only assessment work was being done (Castello, 1921,
p. 110). Late in 1927 the Champion mine was acquired along with a
large group of other mines in the Colorado district by Consolidated
Gold Fields of Mariposa, Inc., in which the present owner was the
principal partner (Laizure, 1928, p. 84). No sustained mining was
done before the depression years starting in 1929 and little has been
done with the mine in recent years.
The Champion vein strikes N. 65-70° W. and varies only a few de-
grees from vertical. The average width is perhaps 4 feet but it locally
thickens to as much as 12 feet. Vein matter is in part massive milky
quartz and in part a ribbon-structure of laminated white and glassy
quartz including thin sheets of slate wall-rock. Ore minerals are pyrite,
galena and native gold. The vein is on or close to the contact between
slaty and schistose metasediments of the Paleozoic Calaveras group
and hornblende granodiorite. The granodiorite is cut by several granitic
porphyry dikes the largest of which parallels the strike of the vein and
is about 300 feet northeast of it.
Workings in 1919 consisted of a 96-foot shaft with levels at 60 and
90 feet. On the 60-foot level the east drift was 78 feet and the west 50
feet. On the 90-foot level there is a 60-foot west drift only. In addition
there are shallow workings strung out along the vein for over 1300
feet. In August 1955 the shaft was open to a depth of 40 feet.
Clearinghouse Mine (Original and Ferguson, Anderson). Location:
Sees. 16, 21, T. 3 S., R. 19 E., on the Merced River and State Highway
140 at Clearinghouse, 7 miles west of El Portal. Ownership : Mrs.
Frank E. Gallagher, 211 26th St., Merced, California, owns ten pat-
ented claims, the Original, Original No. 2, South Original Extension,
El Portal, Anderson, North Extension of the Anderson, Golden Rule,
Golden Rule No. 2, Moonstone and Moonstone No. 2, totaling about
190 acres.
History : The more westerly group of claims, best known as the Fer-
guson mine, but also called the Anderson mine, was discovered about
1860, probably by the Ferguson brothers. During the 1860s the mine
was operated by the Fergusons and a large tonnage of high-grade ore
was extracted. The Sonora Herald, February 22, 1868, states that 174
oz. of gold were recovered during a week of operation of the 8-stamp
mill at the Ferguson mine. This mill processed 6 tons of ore in 24
hours so that the ore must have run several ounces of gold per ton.
In 1870 the mine was sold by the Fergusons to a San Francisco com-
pany for $80,000 (Min. and Sci. Press, vol. 21, no. 15, p. 252) but
ownership had reverted to E. Ferguson by 1871. In February 1871,
the ore was averaging $44.00 per ton (Min. and Sci. Press, vol. 23,
no. 16, p. 244) and the mill had been enlarged to 15 stamps. The mine
was intermittently idle during the middle 1870s but was operating full
scale in 1878 under the ownership of E. Ferguson, with Robert Frances

as superintendent. Ore at that time ran from $10 to $40 per ton, but
in 1879 some ore ran between $75 and $100 per ton (Min. and Sci.
Press, vol. 37, no. 22, p. 34; vol. 38, no. 12, p. 181).
As early as 1870 the main adit had reached a length of 1100 feet.
About 1871 an underground shaft or winze was sunk from the end
of the 1100-foot tunnel. This was 100 feet deep in February 1871 (Min.
Sci. Press, vol. 22, no. 8, p. 115). About 1878 a second underground
shaft was sunk from the main adit at a distance of about 1000 feet
from the portal. This No. 2 shaft was 200 feet deep by fall of 1878
(Min. and Sci. Press, vol. 37, no. 14, p. 341).
Through 1880 the Ferguson mine continued to be an active producer
and in July 1880, fifty pounds of specimen gold-quartz was sold to a
jeweler for $1200 (Min. and Sci. Press, vol. 41, no. 18, p. 273). From
1881 to 1934 the mine was largely inactive. It was bonded for a short
time in 1899 to J. F. Joseph and associates of Sonora (Eng. and Min.
Jour., vol. 68, no. 16, p. 465) ; to L. and E. Mason, Incline, in 1905;
and to George S. Barber of Oakland in 1910. There was no recorded
production under any of these operators. By 1920, ownership had
passed to Mrs. S. A. Hall and Anna K. Sherwood under the name Fer-
guson Consolidated Gold Mines, but the mine remained idle.
The more easterly group of claims, called the Original mine, was first
located in 1908 (Laizure, 1928, p. 107). It was operated almost con-
tinuously from 1911 to 1933 by the Original Mining and Milling Com-
pany (E. C. Kocher, pres., G. M. Egenhoff, mgr., J. W. Warford,
supt.), from Jan. 1, 1933 to October, 1934 by a group of lessees headed
by J. W. Warford (Laizure, 1935, p. 40), and from 1934 to 1937 under
lease by San Juan Ramsey Company (Boston, Mass., W. C. Smith,
pres., A. S. Wyner, Incline, mgr.). About 1925 the claims of the
Ferguson mine were acquired by the Original Mining and Milling
Company and all ten claims of the present property were patented
during that year (Laizure, 1928, p. 107). In December 1937 a flood
washed out both the Yosemite Valley Railroad and the state highway.
The mine closed down and has since been idle (Julihn and Horton,
1940, p. 143).
The Clearinghouse mine has been among the ten highest-producing
mines in Mariposa County, the total production being in excess of
$3,350,000. Claims of the Ferguson mine have yielded an early esti-
mated production of $1,250,000 (Julihn and Horton, 1940, p. 134) and
a recorded production between 1935 and 1940 of $107,000 for a total
of $1,357,000. Between 1911 and 1937 the claims of the Original mine
yielded 79,636.79 oz. of gold, 25,364 oz. of silver, 340 pounds of copper
and 134 pounds of lead from 175,156 tons of ore. This amounted to
slightly more than $2,000,000 at the prevailing gold prices, but would
amount to about $2,797,900 at the present price of gold.
Geology: The Original and Ferguson veins lie on opposite sides of
a north-trending sill-like mass of coarse-grained granitic rock approxi-
mating biotite granodiorite. The granodiorite has been intruded into
metasediments of the Paleozoic Calaveras group roughly parallel to
the slaty cleavage and schistosity. The Original vein, lying on the east
side of the mass strikes N. 7°-10° E. and dips 78° east. To a depth of
about 400 feet the vein lies entirely in slaty metasediments, but below
that depth the wall rocks are chiefly granodiorite (Young, 1929, p. 46).
Nos. 1 and 2] mines and mineral deposits, mariposa county 89
The Ferguson vein, lying on the west side of the granitic mass, strikes
about N. 21° E. and dips about 70° west. In general, it follows the
contact between the granodiorite and the metasediments. Metasedimen-
tary rocks on the dump include slate, quartz-biotite hornfels, graphite-
mica schist and some quartz-mica gneiss. According to Young (1929,
p. 46) the slaty cleavage dips 40° east near the apex of the Ferguson
vein but steepens to 78° at adit level. Three lateral quartz veins join
the Ferguson vein at various angles from a northwesterly direction,
the Spanish, Golden Rule and Moonstone veins. These have been super-
ficially explored and their form is not yet certain.
Five ore shoots have been discovered in the Ferguson vein north of
the underground shaft. These are roughly parallel and pitch north
at an average of 60°. The shoots average 4-5 feet thick and 100 to 150
feet wide. Two of the five shoots have been stoped to depths exceeding
1000 feet, as measured on the axis of pitch. Four ore shoots have been
worked in the south end of the Ferguson mine. These pitch north at
angles between 40° and 70°. The character of ore is similar in most
ore-shoots, arsenopyrite, galena, sphalerite and native gold occurring
in ribbon quartz. In general, the sulfide content of the ore is about twice
as great in the shoots of the Ferguson vein than in shoots of the Original
vein (Julihn and Horton, 1940, p. 145).
Mine Workings : Inasmuch as the workings were not accessible to the
authors, the following mine descriptions have been drawn largely from
Young (1929) and Julihn and Horton (1940). Julihn and Horton were
the last authors to visit the Clearinghouse mine while it was still in
operation.
There are extensive workings on both the Original and Ferguson
veins. The Original vein workings are entered by a 175-foot, west-
trending crosscut adit which intersects the vein 180 feet below the out-
crop. The portal of this adit is on the west side of a ravine at an
elevation of approximately 1600 feet. A 2-compartment underground
shaft or winze, inclined 78° east has been sunk from near the end of
the crosscut adit to an inclined depth of approximately 1170 feet. The
shaft serves 9 levels (below the adit level), the 200, 300, 400, 500, 650,
750, 850, 950 and 1100-foot levels. A 250-foot vertical winze with short
levels at 1125 and 1150 feet is sunk from the 1100-foot level at a point
150 feet north of the main shaft and there is a 150-foot raise to the
surface from the adit level. The total vertical depth explored in the
Original vein is, therefore, approximately 1530 feet. Development work
north of the main shaft amounts to an average of 1300 feet of drifts
per level, the longest drifts being on the 650 and 950 levels. South of
the main shaft the maximum distance penetrated is about 265 feet
with some stoping between the 400 and 850 levels. There are extensive
stoped areas north of the shaft between the adit and the 1100 levels.
From the 650 level of the Original workings 510 feet north of the
Ferguson shaft a 1200-foot crosscut connects with the Ferguson vein.
Owing to a faulty survey, the 600-foot drift along the vein from this
crosscut did not strike the number 1 ore body and the drift was never
connected to the other workings above it on the Ferguson vein. In
addition to the crosscut and drift from the Original workings, the
Ferguson vein is developed by 5 adit levels which are top to bottom,
the D-, C-, B-, A- and 100-levels. There is also an unused former A-level
90 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
roughly 50 feet above the main level (A or haulage level). The A and
100-levels are slightly over 1200 feet long; the others average less than
half as long. From the A-level, a 450-foot winze or underground shaft
has been sunk above 400 feet from the portal. This shaft serves the
200- , 300- and 400-foot levels. A second winze or underground shaft
connects the A- and 100-foot levels about 600 feet from the portal of
A-level, and there is a 200-foot winze sunk about 375 feet north of the
portal of the 100-level. The 100-foot winze sunk from the end of the
1100-foot A-levelin 1871 and a 200-foot winze sunk from A-level 1000
feet from the portal in 1878 do not show on the latest available mine
diagrams. The latter apparently was stoped out and the former may be
filled with gob or debris. Ore has been stoped to a vertical depth of
slightly more than 450 feet and over a vein length of about 1000 feet.
About 1800 feet north and 1350 above the portal of the A-level are
a group of old Spanish workings consisting of several short drifts with
superficial connecting workings. These apparently are on the North
Extension of the Anderson claim.
Grade of Ore: The ore milled from the Original vein from 1911 to
1934 averaged 0.454 oz. of gold, and 0.14 oz. of silver (calculated from
U. S. Bureau of Mines figures) and a little copper and lead. Zinc al-
though present was not recovered. The Original vein ore from 1935
to 1940 average 0.274 oz. of gold and 0.083 oz. of silver. There is no
indication of the quality of the ore from early operations except the
historical notations made earlier in this account.
Colorado Mine. Location: Near the center of sec. 27, T. 4 S., R. 18
E., M.D. on the east side of Long Canyon Creek a quarter of a mile
west of Colorado School or 5 airline miles north of Mariposa. Acces-
sible by graded dirt road via either Saxon or Sherlock Creek roads.
Ownership: Property is jointly owned by Corinne Kratzer (J), 555
Thirty Second Ave., Richmond, California, F. E. and P. W. Jud-
kins (i), 2817 San Pablo Ave., San Pablo, California, Charles and
Irma St. Johns (£), 619 Humboldt St., Richmond and Ellen R. "Weston
(-J), 443 Ninth St., Richmond. Property consists of 1 patented frac-
tional claim of 11 acres and 2 unpatented claims.
Little of the early history of the Colorado mine has been recorded.
It already had extensive workings in 1914 when the mine was being
developed by P. W. Judkins, C. H. Weston and I. L. Dearborn of
Mariposa. Ownership of the mine still remains with these individuals
or their heirs.
The Colorado vein averages 1-| to 2 feet wide, strikes N. 50° W.
and dips 60°-80° NE. Locally it reaches a width of 7 feet. Wall rocks
are chiefly slate and sandy metasediments belonging to the Paleozoic
Calaveras group. The metasediments have been intruded by green-
stone dikes and sills 1 foot to 3 feet wide. The strike and dip of the
slaty cleavage near the shaft is roughly parallel to the vein and to the
bedding planes. Vein matter is chiefly banded quartz carrying free
gold and a little pyrite. According to Julihn and Horton (1940, p. 153)
the ore shoots are 30 to 75 feet long and pitch north at about 45°.
Workings are reported to consist of a 200-foot inclined shaft, a 500-
foot working level that intersects the shaft 125 feet from the collar, and
a 200-foot drift on the 95-foot level south of the shaft (Julihn and
Horton, 1940, p. 153). According to Laizure (1928, p. 83) there is a
Nos. 1 and 2] mines and mineral deposits, mariposa county 91
stope above the 95-foot level 120 feet long and 35 feet high and Julihn
and Horton state that most of the known ore has been stoped to the
surface above the 95-foot level. The workings are caved and inaccessible,
and there were no buildings or equipment on the property in August
1954.
Nothing is recorded on the early production of the Colorado mine.
In the late 1920 's, about 2500 tons of ore was mined which ran $10 to
$11 per ton with some "development rock" running $8 (Laizure, 1928,
p. 83). Between 1915 and 1938, 7129 tons of ore was milled which
yielded 2011.91 oz. of gold and 351 oz. of silver (U. S. Bureau of Mines
records). The average tenor of ore was, therefore, 0.282 oz. of gold per
ton or about $15.87 at the present price of gold. The total production
of the mine probably does not greatly exceed $50,000.
Cotton Creek (Hanser) Mine. Location: NW J, sec. 24, T. 4 S.,
R. 16 E., M.D., on Cotton Creek \ mile east of the Hunter Valley road
or 1\ airline miles northeast of Hornitos. Ownership : not determined.
Last known operator (1939) was Cotton Creek Mining Company, W. H.
Hauser, Richmond, California, manager.
In July, 1937, the Cotton Creek Mining Company began develop-
ment of a hitherto little-known prospect (Julihn and Horton, 1940,
p. 120). This company operated the mine until 1939 since when it has
been idle except for assessment work.
The vein, which averages about 2| feet wide, strikes N. 40° W. and
dips 20-25° S. In places it reaches a width of 5 feet. Vein matter con-
sists of quartz, auriferous pyrite, chalcopyrite, galena, and native gold.
Large areas of wall-rock adjacent to the vein have been impregnated
with pyrite. Wall rocks are greenstone (meta-augite andesite) of the
Upper Jurassic Penon Blanco formation.
Workings consist of a shaft inclined 20° to the S.W. and an unknown
number and footage of drifts. In August 1938, the shaft was 175 feet
deep with 75-foot drifts north and south from the shaft on the 100-foot
level (Julihn and Horton, 1940, p. 120).
In August 1954 the mill and hoisting equipment were in good con-
dition, but the shaft was caved just below the collar and the headframe
was in need of repair. Equipment includes a hoist, compressor, jaw
crushers, Straub mill, rake classifier and other miscellaneous equip-
ment. The shaking tables and flotation cells which once were part of
the mill had been removed.
Between 1937 and 1939 the mine produced 4897 tons of ore which
yielded 1304 oz. of gold, 725 oz. of silver, 1669 lbs. of copper and 1730
lbs. of lead (U. S. Bureau of Mines records). According to Julihn
and Horton (1940, p. 120) the ore averaged $15 per ton at the present
price of gold, but by U. S. Bureau of Mines figures the yield was
nearer $11 per ton.

The Diltz mine was discovered during the 1860s either by Tom Early
or by Captain John S. Diltz. The Mariposa Gazette of April 10, 1886,
states that Early worked the mine before Captain Diltz became owner,
taking out 232 oz. of free gold by sluicing and sending 250 tons of ore
to the Whitlock mill which returned $32 per ton. Captain Diltz oper-
ated the mine under very adverse circumstances from the 1870s until
the time of his death in 1895, chiefly by washing the surface soil and
soft, brecciated parts of the vein. In 1884 a landslide buried the
Kickard shaft (the most northerly of several shallow shafts) and land-
slides seriously hampered operations in January, 1886. In 1886 Diltz
recovered a mass of gold weighing 10 lbs. 6 oz., avoirdupois, for which
he received $2000 (Min. and Sci. Press, vol. 52, no. 16, p. 260).
Throughout the period of Diltz \s ownership the mine was not equipped
with a mill and very little ore was custom-milled elsewhere. Early in
1887 the mine was leased for a short period by Joe Shantz and Sam
Jacoby and in 1890 George Stewart worked the mine for a time in
partnership with Captain Diltz (Min. and Sci. Press, vol. 16, no. 13,
p. 216).
After the death of Captain Diltz in 1895, the mine was held for a
time as part of the Diltz estate and then was acquired by Hugh
Devaney. In 1914 it was purchased from the Devaney estate by Mr. and
Mrs. S. J. Harris of Jerseydale and some work was done at the mine
that summer by the Mariposa Mines and Development Company, a part-
nership of C. A. Schlageter and T. L. Diven (Castello, W. O., 1921,
p. 113). By 1919 ownership had passed to Mrs. Jenny Diven of Oak-
land, California. In 1927, George Ahart of Mariposa leased the mine
from Mrs. Diven and installed a 10-stamp mill (Laizure, C. M., 1928,
p. 85). The present owners acquired the property in 1931 and operated
it during the periods 1931-42 and 1943-50. In May 1932, a mass of
specimen gold weighing 52 pounds, troy, was taken from the 100-level.
It yielded 43 lbs. 2 oz. of gold worth $10,707 at the old price of
$20.67. Another specimen was recovered weighing 20 lbs. 2 oz. worth
$3,862. Pockets containing $100 to $500 in free gold are not unusual.
The total estimated production of the Diltz mine is between $750,000
and $1,000,000. From 1924 through 1954 the mine produced 81,657
tons of ore from which 21,135 oz. of gold and 3395 oz. of silver were
extracted (compiled from records of the U. S. Bureau of Mines). These
figures do not include the period during which Captain Diltz operated
the mine nor the specimen gold which was marketed elsewhere than
the mint. Most of the recorded production was made since the price of
gold was raised to $35 an ounce. The average tenor of ore milled was
about 0.24 oz. per ton. The Mariposa Gazette of April 25, 1885, states
that ore and float from the surface workings averaged $15 per ton (at
the former price of gold). A later entry for December 12, 1885, indi-
cates that the surface material averaged $14 per ton by sluicing and
that the remaining uncrushed ore ran $30 per ton.
The veins at the Diltz mine cut an ancient series of pyroxene andesite
greenstones of probable Paleozoic age. Both intrusive and flow-rocks
as well as pyroclastic masses are represented in the series. The principal
vein strikes N. 10° E. and dips 35-40° east. At depth it has an average
width of about 2-| feet, but in places reaches a width of 10 feet. Near
the old open workings of the mine northeast of the main shaft, the
94 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
vein flattens or rolls and feathers out into the wall rocks in places be-
coming ,15-20 feet thick. According to old accounts the vein never
apexed at the surface. The greenstone of the hanging wall differs con-
siderably in appearance from that of the footwall side which may indi-
cate a considerable throw on the fault the vein occupies.
In addition to native gold, ore minerals include arsenopyrite, pyrite,
chalcopyrite, tetrahedrite and galena. Gangue minerals include milky
and ribbon quartz, calcite and oxides of iron and manganese. Accord-
ing to Julihn and Horton (p. 146, 1940) the chief sulfide mineral is
arsenopyrite. Ore shoots have been found in the vein over a distance
of more than 1400 feet of strike length. These average about 350 feet
long (Laizure, 1928, p. 29).
The principal working is a 625-foot inclined underground shaft sunk
from the compressor level 200 feet below the top of the vein and 300
feet from the portal. This shaft serves 6 levels aggregating 4700 feet of
drifts (Julihn and Horton, 1940, p. 146). There are also several shallow
inclined shafts and several tunnels at various places along the vein
which are now largely caved and inaccessible. The vein is well exposed
in a glory hole 300 feet north of the portal of the main tunnel. When
active, the mine made about 30,000 gallons of water per day (Julihn
and Horton, 1940, p. 146).
The mill is equipped with an 8" x 20" jaw crusher, ore bins, fifteen
1250-lb. stamps, screens, amalgamation plates, drag classifier, and de-
watering cones. Eighty percent of the water is returned to the mill
circuit when the mill is operating. Mine and mill have been largely idle
since 1952.
Dolman (Oyler Lode, Hickman, Bear Valley Mountain) Mine. Loca-
tion : SB J, sec. 29, NWJ sec. 33, T. 4 S., K. 17 E., M.D., 1£ miles south
of Bear Valley. Ownership : Not determined ; probably Ellen T. Simp-
son, et al.
According to Laizure (1935, p. 31), the Dolman mine was discovered
in 1894. In 1902 Charles Adair and Henry Oyler leased the mine from
the Mariposa Commercial and Mining Co. and a 50-foot shaft was sunk
(Min. and Sci. Press, vol. 75, no. 1, p. 608). During the period of activity
some ore was mined and shipped. Laizure (1935, p. 31) states that the
mine ' ' . . . produced about 800 tons of ore which had an average value
of $13 per ton . . . ' \ Official records of the Mariposa Commercial and
Mining Company, however, indicate that only 59.1 tons of ore was
shipped which returned $756.78 or an average of $12.80 per ton. In
1934 the property passed into the hands of a companj^ in which R. L.
and E. P. Hickman of San Francisco and Phil B. Dolman of Bear
Valley were the chief active participants. During 1939 and 1940 some
393 tons of ore was shipped which yielded 24 oz. of gold and 7 oz. of
silver, returning about $2.15 per ton (U. S. Bureau of Mines records).
The mine has been idle since 1940.
The Oyler vein has a general strike of N. 35° W. and dips 60° south-
west. This direction of dip is unusual in mines of this area which gen-
erally dip northeast. It occupies a well-defined shear zone which is
traceable for 2 miles. Wall rocks are pyroxene andesite greenstones
of probably Upper Jurassic age. The vein varies from a fraction of a
foot to 5 feet wide. Ore shoots are short — commonly less than 30 feet
Nos. 1 and 2] mines and mineral deposits, mariposa county 95
(Laizure, 1935, p. 32). Vein matter is chiefly milky quartz with pyrite,
pyrrhotite, chalcopyrite, oxides of iron and native gold. About 60 per-
cent of the gold is found in sulfide minerals.
The principal group of workings, developed mainly by Hickman and
Dolman between 1934 and 1940, consist of a 265-foot inclined shaft and
1445 feet of drifts on four levels, the 100, 175, 200, and 250. The longest
drift, driven 760 feet north of the shaft is on the 200-level. In this drift
an ore body was encountered 625 feet from the shaft which assayed $8
per ton (Julihn and Horton, 1940, p. 129). There is a main ore shoot
south of the main shaft penetrated on the 100- and 175-foot levels and
two smaller ore shoots were found on the 175-foot level. Some ore in
the main shoot on the 175-foot level ran $18 per ton, according to Julihn
and Horton. A geologic map and sections of the mine together with some
sampling data are found in Laizure (1935, p. 31).
Doss (Doss and Thome, Ginaca, Brooks) Mine. Location: Sees. 21,
28, T. 5 S., R. 16 E., M.D., 2\ airline miles southeast of Hornitos or 2
miles northwest of Indian Gulch. Accessible by 2 miles of ungraded
dirt road from the paved Hornitos-Mt. Bullion road. Ownership : Frank
Trabucco Jr., Hornitos, California, owns 2 patented fractional claims,
the Doss and the Thorne Extension, totaling 18.27 acres.
The Doss mine was discovered sometime prior to 1870. In 1874 the
shaft was down 110 feet and averaged 10 feet wide to that depth. At
that time the owner was a Mr. Brooks of Hornitos. One lot (200 tons)
of ore ran $17 per ton and another of 400 tons yielded between $10 and
$11 per ton (Min. and Sci. Press, vol. 29, no. 9, p. 85) plus a sulfide
concentrate assaying $24 per ton. Storms (1896, p. 218) visited the
mine in 1896, finding the shaft still 110 feet deep. Gold to the amount
of 677.25 oz. was recovered from an unknown tonnage of ore in 1897.
By 1920 ownership had passed to L. A. Ginaca and C. Ginaca of San
Francisco. The shaft had been deepened to 400 feet and an adit level
driven 475 feet. The 200-level had 300 feet of drifts. In 1933 the mine
was under option to A. D. Hadsel and then was acquired by the Doss
Mining Company of San Francisco who operated it until July, 1934.
Between 1934 and 1938 it was intermittently active under several op-
erators, but has been idle since 1938.
The vein at the Doss Mine strikes N. 40-45° E. and dips 55° south-
east. Wall rocks are chiefly slaty and schistose volcanics belonging to
the Upper Jurassic Amador group described by Taliaferro (1943, pp.
282-284). The vein averages 8-10 feet wide, reaching a maximum width
of about 22 feet (Laizure, 1935, p. 114). Ore shoots average 250 feet
long as measured along the strike and ore shoots have been discovered
over a vein length of 1000 feet and to a depth of 400 feet. Vein matter
consists of milky quartz with pyrite, galena, sphalerite, chalcopyrite
and gold.
Workings consist of a 250-foot (vertical depth) inclined shaft, the
last to be worked, and an older shaft 400 feet deep. There is also a
540-foot adit. None of these are in working condition.
The early production of the Doss Mine was not recorded other than
the figures listed above. In 1929, thirty-eight tons of ore was milled
which yielded 39.95 oz. of gold and 76 oz. of silver. Between 1933 and
1938, ten thousand two hundred and ninety-five tons of ore was milled
which yielded 2025.39 oz. of gold and 1713 oz. of silver or an average
96 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
of about $7 per ton. The total recorded production of the mine is
approximately $94,400 and the estimated production is in excess of
$100,000.
Duncan (Lost Douglas) Mine. Location : Sees. 16 and 21, T. 5 S., R.
16 E., M. D., just south of the Hornitos — Mt. Bullion road. Adjoins
Martinez mine on the northwest. Ownership : George D. Turner, Rt. 1,
Box 1049, Ceres, California, owns one patented claim of 44 acres.
The Duncan mine is a very old property dating back to before 1870.
The first owner of record was Jerome B. Brown who acquired the prop-
erty in 1873 or 1874 (Min. and Sci. Press, vol. 35, no. 18, p. 278).
Brown operated the mine intermittently until 1895 or 1896 when owner-
ship passed into the hands of William and George Turner of Hornitos.
In addition to ore run through the mill Brown took out a $3000 pocket
of specimen material in 1877 (Min. and Sci. Press, vol. 35, no. 8, p. 278)
and a $1000 pocket in 1888 (Min. and Sci. Press, vol. 57, no. 24, p. 400).
A 5-stamp mill was operating on the property as early as 1885 (Min.
and Sci. Press, vol. 50, no. 26, p. 416). Except for a short period of
activity in 1917 there is no record of activity at the Duncan mine until
1920. In March 1920, Onito and Tura took out a pocket of specimen ore
yielding $1000 (Castello, 1921, p. 114). In 1926 the Duncan Mining
Company was formed in which Bert Thurber and D. L. Onito were the
principal active partners. Considerable ore was milled in 1927 by this
company. The mine was operated under lease for a time in 1932 by
Austin Davis of Hornitos, in 1933 by Chris Peterson and in 1934-35 by
H. L. Berkey and his associates David Onito and J. A. Bodies (U. S.
Bureau of Mines records; Laizure, 1935, p. 32). The mine has largely
been idle since the late 1930 's and there is no equipment on the
property.
The vein system at the Duncan mine is well denned at the surface,
strikes N. 50° W. and dips about 45° NE. At the surface it varies
from 2 to 5 feet wide and consists chiefly of vuggy quartz and pyrite.
Although several ore shoots of fair grade have been worked, the mine
is noted for its pockety character and the last ore milled in the middle
1930 's was of marginal grade. Wall rocks are schistose greenstone,
quartz biotite schist and quartz biotite hornfels derived from volcanic
tuffs and flows of the Upper Jurassic Amador group.
Workings consist of a series of open pits and caved shafts strung out
along the vein for nearly half a mile. None were accessible in September
1954. The main shaft was down 325 feet along a 45° incline in 1934
(Laizure, 1935, p. 32).
Production records on the Duncan mine are too incomplete to give
much indication of the total yield of the mine. In 1897-98, two hundred
and forty -six oz. of gold was recovered from an unknown quantity of
ore. In 1927, five hundred tons of ore yielded 219.82 oz. of gold and 70
oz. of silver (U. S. Bureau of Mines records). From 1932 to 1935, eleven
hundred and forty-six tons of ore yielded 90 oz. of gold and 45 oz. of
silver (U. S. Bureau of Mines records).
Early (Revel, Louisa, Felix, George Placer) Group. Location : Sees.
20, 21, T. 4 S., R. 19 E., M. D., li miles northwest of Jerseydale or 1\
airline miles northeast of Mariposa. Accessible from Mariposa by about
10 miles of paved road, via Triangle Road, Darrah and Jerseydale, and
Nos. 1 and 2] mines and mineral deposits, mariposa county 97
2 \ miles of graded dirt road from Jerseydale. Ownership : Robin H.
Jackson and Edythe E. Jackson, Box 142, Mariposa, California own a
patented property of 80 acres, recorded as the George Placer mine,
which includes the former Early, Louisa, Revel and Revel No. 2 lode
claims. Also the Felix lode claim embracing 19.16 acres.
Recorded history of the Early mine reaches back to 1884 when Rice
and Ferguson operated the property. At that time there was a shaft
100 feet deep on the Early claim and a 260-foot tunnel and 8-stamp
mill on the Mt. View claim (Min. and Sci. Press, vol. 49, no. 16, p. 2488,
1884). The name Mt. View has been dropped, but it may be the same
as the Revel. By 1902 ownership had passed to August and Eli Revel
who operated the mine for a short time that year with A. T. Mitchell
as superintendent (Eng. and Min., Jour., vol. 74, no. 10, p. 320, 1902).
Between 1902 and 1916 it was active for short periods of time under
various lessees. In 1916 it was leased by Mrs. C. N. Mclntyre who
opened the old drift (presumably on Revel claim) and sunk a 50-foot
shaft from the drift level (Min. and Sci. Press, vol. 112, p. 528, 1916).
After a year of inactivity operations were again started under new
management in June 1917 with George H. Hook as superintendent. A
10-stamp mill was put into operation employing amalgamation, but,
owing to the high percentage of sulfides in the ore, returns were not
very satisfactory (Eng. and Min. Jour., vol. 104, no. 4, p. 408, 1917).
Between 1917 and 1920 activity was curtailed by litigation and various
groups controlled the mine for short periods. After about 12 years
of inactivity, Early Gold Mining Company of Laredo, Texas reopened
the mine under supervision of J. E. Rogers of Mariposa. Rogers op-
erated the mine until 1939. In 1941, George Long of Mariposa worked
the mine for a short period and in 1946, H. N. Hammond of Mariposa
was operator. The present owners acquired the property in the late
1940 's and have intermittently worked on the mine since that time
except for a short period in 1951 when some ore was mined and shipped
by H. H. Odgers and I. R. Toye of Midpines.
Two sets of east- and northeast-trending quartz veins cut hornblende
quartz diorite. Most of the veins average between 2 and 3 feet wide, but
widen locally to as much as 6 feet. The principal developed vein on
Revel claim strikes roughly east and is vertical. The most thoroughly
explored vein on the Early claim strikes N. 25° E. and dips 60° SE.
Vein matter is chiefly quartz and pyrite with some chalcopyrite,
argentiferous galena and light yellowish-brown native gold, but there
are showings of scheelite in the vein matter and in the quartz diorite
adjacent to the veins. Most of the high-grade scheelite ore is in stringers
2-4 inches wide.
The present extent of the mine workings could not be ascertained in
September 1954 as all were inaccessible because of caveins and flooding.
In 1914 there was a 16-foot shaft, surface trenches and 2 adits 50 and
60 feet long on the Louisa claim (Lowell, F. L., 1916, p. 586) ; an adit
800 feet long, overhand-stoped to a height of 150 feet, and a 40-foot
crosscut-tunnel on the Early claim; and a shaft 150 feet deep with
several hundred feet of drifts on the Revel claim. Considerable work
was done on the claims since 1914 so the above list of workings un-
doubtedly is incomplete.
4 — 49184
98 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
In September, 1954, exploration was progressing by use of bulldozer
cuts which had uncovered several veins. Soil mantle is 18-20 feet deep
in most places, but commonly carries considerable gold. Part of this
was derived from the weathered upper portions of the vein and partly
from old mill tailings. Some of the mantle material may prove rich
enough to process.
Production records for the Early mine are incomplete but a total of
$22,600 was recorded between 1909 and 1952. From 1909-1914, 478 tons
of ore were mined which yielded 251.02 oz. of gold and 50 oz. of silver.
From 1917 to 1920 a total of 697 tons of ore mined yielded 259.34 oz. of
gold and 364 oz. of silver. For the period 1932-33, seven hundred tons
of ore was processed which yielded 264.47 oz. of gold and 147 oz. of
silver. Between 1934 and 1946 six hundred and fifty tons of ore yielded
156.34 oz. of gold, 207 oz. of silver and 1231 pounds of copper (U. S.
Bureau of Mines records).
Feliciana Mine. Location: Sees. 12, 13, T. 4 S., R. 18 E., sees. 7, 18,
T. 4 S., R, 19 E., M.D. Accessible by way of State Highway 140 and
2\ miles of the graded dirt road up Trabucco Creek. Trabucco Creek
road joins Highway 140 three miles north of Midpines. Ownership :
Gold Ledge Mining Company, c/o Walter Gleeson, Pacific National
Bank Building, San Francisco, California owns one patented claim,
the Feliciana (20 acres) and 13 unpatented claims.
The Feliciana mine was discovered in the 1850s and was operated
by Mexicans during the 1850s and early 1860s. In 1866 the mine was
equipped with a 5-stamp mill and had a shaft 190 feet deep. Louis
Trabucco of Bear Valley owned and operated the mill and had a part
interest in the mine (Min. and Sci. Press, vol. 13, no. 8, p. 118, 1866).
In the summer of 1866 fire destroyed the mill and later that year the
mine was purchased by a San Francisco Company (Min. and Sci. Press,
vol. 23, no. 18, p. 276). In December 1871 the mine was leased by J.
Dolan of Bear Valley and reconstruction of the mill was started. By
1875 a 10-stamp mill had been built, a 300-foot tunnel driven and a
300-foot shaft sunk. In 1896 the mine was sold to E. S. Davis of Fresno.
By 1914, ownership had passed to J. B. Campbell of Fresno (Lowell,
1916, p. 582). Thomas Doyle leased the mine from Campbell in 1917,
after a long period of inactivity, but this activity was short lived, the
mine having become idle by 1920 and ownership having passed to Mrs.
Campbell. In 1925, the Feliciana Gold Mining Company, Inc. was
organized with M. Farber as president and Pauline Farber as vice
president, both of San Francisco (Laizure, 1928, p. 86). This company
operated several other mines in the Briceburg district during the late
1920s, but had largely ceased operations by 1930. About 1931 the
mine was acquired by the present owners and in 1933 the Gold Ledge
Company began driving a long tunnel designed to intersect the vein
at a depth of 900 feet. By September 1934 this tunnel had reached a
length of 1186 feet but work on it was carried little further and was
discontinued late in 1934 (Laizure, 1935, p. 33). In 1941 the mine
was leased by Russell J. Wilson with William Bessler as mine superin-
tendent. For a time ore was milled at the Buffalo mine, but in 1942 a
mill was moved to the Feliciana from the Black Oak mine in El Dorado
County (Eng. and Min. Jour., vol. 142, no. 10, p. 76, 1942). Closed
Nos. 1 and 2] mines and mineral deposits, mariposa county 99
down by War Production Board Order L-208, the mine has been idle
since 1943 except for maintenance and assessment work.
The total recorded production of the Feliciana mine is approximately
$159,500, chiefly in gold and silver but also from a little lead and
copper. Between 1924 and 1934 a total of 3231 tons of ore yielded
2412.7 oz. of gold or an average of 0.74 oz. per ton. From 1941 to 1943
a total of 4428 tons of ore yielded 2873.1 oz. of gold and 465 oz. of
silver or an average of about 0.65 oz. of gold per ton.
Well-defined and traceable for several thousand feet at the surface,
the Feliciana vein averages between 2^ and 3i feet wide, strikes N.
35-40° W. and dips 70-75° SW. It is exposd on rugged topography
through a vertical distance of nearly 1000 feet. Vein matter consists
of native gold, galena and chalcopyrite in a gangue of quartz and
pyrite. A steeply dipping secondary vein intersects the main vein at an
angle of 20° and the principal ore shoot has developed along this
intersection (Laizure, 1928, p. 86). Two minor veins also join the main
vein from the east or footwall side. These are largely unexplored.
Wall rocks are a series of northwest-trending, steeply tilted meta-
sediments belonging to the Paleozoic Calaveras group. Slate, phyllite
and graphitic and hornfelsic slates and schists are the principal rock
types. The metamorphic series is cut by several small quartz diorite
dikes.
Principal workings on the Feliciana claim are a 340-foot crosscut
adit, with several hundred feet of drifts both north and south of the
adit, and a shaft at least 190 feet deep. A winze from the crosscut adit
connects with a lower level and drifts. The authors have no information
on the extent of these workings. In August 1954, the adit could be
entered for at least 100 feet and readily could be cleaned out beyond
that point. The shaft was caved and the access road in poor condition.
A 700-foot tunnel mentioned by Castello (1921, p. 115) could not be
located and is presumed to be caved. This was reported to have several
hundred feet of drifts. Most of the late work done on the mine has
been from the lower tunnel on the Ace-in-the-Hole claim, the one driven
in 1933-34. This is driven at an elevation of 3100 feet or 550 feet below
the adit on the Feliciana claim. It is 1400 feet long and is connected
with the older workings by an 80-foot raise. A second raise from the
adit contacts the vein but is not connected with the upper workings.
French Mine. Location : Sees. 9, 16, T. 4S., R. 17E., M.D., half a
mile south of the Merced River and 1 mile east of the Pine Tree mine.
Accessible by way of State Highway 49 and 1J miles of dirt road lead-
ing east from the water tanks of the Pine Tree and Josephine mill.
Ownership : Pacific Mining Company, Crocker Building, San Francisco,
California, owns 3420 acres which includes the French, French Pocket
and Evans mines.
The French mine is a very old property active in the earliest days
of mining in the county. Throughout most of its history the mine was
held by the Mariposa Commercial and Mining Company and its prede-
cessors and worked intermittently by various lessees. In 1897 the claims
were jumped by a group headed by Bert McFadden and Robert
Barnett because, through inaccurate surveys, they believed the land
to be outside of Las Mariposas Grant (Min. and Sci. Press, vol. 75,
100 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
no. 4, p. 80, 1897). The French mine and several others in the vicinity
were acquired by the Pacific Mining Company in the early 1930s.
Charles Sommers, et al., operated the French mine under lease in the
middle 1930s. The last work done at the mine was in 1948.
The total recorded production of the French mine since 1903 is about
$116,750. The early production may have been several times this
amount. Ore taken out in 1903 averaged $44.16 per ton; in 1924 the
average was $16.53 and in 1935-48 the yield was $13.99 per ton.
Two roughly parallel quartz veins cross the property. The principal
vein averages about 20 inches wide, strikes N. 70° E. and dips 30° S.
(Laizure, 1935, p. 33). Wall rocks are meta-pyroxene andesite green-
stone of unknown age and slaty metasediments belonging to the Paleo-
zoic Calaveras group. The principal working is a crosscut adit 155 feet
long with drifts on the main level totaling 660 feet. Ore has been stoped
almost continuously above the main level and there are seven stope-
openings connecting with the surface. Two inclined shafts, each about
150 feet deep, connect with the main level. These are spaced about 50
feet apart. Both are in need of cleaning out. They connect with a lower
level about 100 feet long driven about 38 feet below the main level. The
total footage of workings aggregates 1048 feet.
Garibaldi (Blue Lead) Mine. Location : Sees. 4, 9, T. 3 S., R. 18 E.,
M.D., 1 mile west of U.S. Forest Service Kinsey guard station. Kinsey
guard station is 12 miles from Briceburg on State Highway 140 by
good graded dirt road. Ownership : Robert O. Greeves, Box 151, Colum-
bia, California, owns one patented claim of 18.8 acres.
The Garibaldi mine is an old property dating back prior to 1897.
Development of the mine has been hampered by water as the mine
yields up to 600,000 gallons of water a day. Little has been recorded of
the early history of the property. The principal period of activity was
1897-1902 when Garibaldi Mining Company operated the mine with
S. R. Porter as superintendent. During this period a 325-foot inclined
shaft was sunk parallel to the dip of the vein, a 40-foot crosscut to
the vein was run and an unknown footage of drifts run on the vein
from the end of the crosscut. Crosscut and drifts were run from the
300-level. Two 650-gallon capacity skips were kept running day and
night to keep the mine unwatered. The Garibaldi Company operated
a 5-stamp mill and a Huntington mill, processing 30 to 40 tons of
ore daily (Min. and Sci. Press, vol. 84, no. 1, p. 11; vol. 84, no. 3,
p. 39; vol. 72, no. 16, p. 503). Early in 1902, forty to sixty ounces
of amalgam was being removed from the plates at the end of
every shift, presumably from 10 to 15 tons of ore milled. This operation
ended in March 1902 because of the expense and the technical diffi-
culties experienced in handling the mine water (Min. and Sci. Press,
vol. 73, no. 20, p. 704, 1902). In 1938 the mine was leased for a short
time by Walter D. McLean of Coulterville. The tailings dump was
worked under lease for a short period in the late 1930s by John P. Mc-
Cormick of Sonora (Julihn and Horton, 1940, p. 136), but the mine has
been idle since that time.
According to Julihn and Horton (1940, p. 135), the Garibaldi vein
strikes a little north of east and dips 45° E. Early notes in the Mining
and Scientific Press mention two parallel veins 1 to 15 feet apart
separated by altered dike rock. Neither vein was exposed at the time of
Nos. 1 and 2] mines and mineral deposits, mariposa county 101
the authors' visit in August 1954. The veins follow close to the contact
between dolomite and a series of schistose metasediments probably
belonging to the Paleozoic Calaveras group. The principal rock types
in the metasedimentary series are slate, graphitic schist, and black
manganiferous chert. The dolomite, which occurs chiefly on the hang-
ing wall side of the vein is blue-gray-to-black and somewhat platy.
Most of the high-grade ore occurs as boulder-like to nodular masses in
a black gouge found between dolomite and the altered dike rock. The
black gouge zone, in many places simply a blue mud, is 8 to 10 feet
thick. Much of the trouble with water came from cavernous dolomite
on the hanging wall side of the vein, but a pump handling 500 g.p.m.
will keep the mine dry.
Early work on the mine was done from two shafts of unknown depth
and numerous open cuts. Work done on the mine from 1900 to 1902 has
already been described. One of the shafts, probably one sunk prior to
1900 was open to a depth of about 100 feet in August 1954. Other
workings were caved.
Geary (Gears) Mine. Location : SE|, sec. 30, T. 4 S., R. 18 E., M.D.
Adjoins the Nutmeg mine on the south and is about a quarter of a mile
west of the Golden Gate and Coronado claims of the Golden Key group.
Accessible via the graded Whitlock Creek-Sherlock Creek road from
State Highway 49, a distance of 5J miles by road from Mariposa.
Ownership : Permit Mining Company, 1063 Howard St., San Francisco,
California, owns one patented claim of 20 acres.
Little has been recorded concerning the early history of the Geary
mine. It apparently was first worked by a series of open cuts from the
surface as there are several hundred feet of almost continuous shallow
Avorkings. The property was purchased in 1898 by Terrill and Schroe-
der who sank a 100-foot inclined shaft, ran several hundred feet of
drifts, and erected a small stamp mill (Min. and Sci. Press., vol. 76,
no. 4, p. 86; vol. 76, no. 20, p. 517, 1898). The mill had a capacity of
14 tons in 24 hours. The amount and tenor of the ore mined at this
time has not been recorded. In 1904 the mine was managed by James
Peck of San Francisco and by 1914 ownership had passed to a Mrs.
Potter. From 1918 to 1938 the owner was listed as J. S. Potter of San
Francisco. It was explored during 1938 by two lessees, H. L. Womacks
of Springdale, California, and Charles E. Farson of Mariposa. Under
these operators a small tonnage of ore was shipped which yielded 0.38
oz. of gold and about 0.1 oz. of silver per ton. Little has been done on
the mine since 1938.
The Geary vein, the same one that crosses the Nutmeg mine, is 3 to 4
feet wide, strikes N. 20° W. and dips 80° NE. From the disposition
of the workings there apparently are several cutter veins crossing and
at least one minor vein paralleling the main vein. Wall rocks are
sheared, somewhat platy pyroxene andesite greenstones of unknown
age.
According to Julihn and Horton (1940, p. 152) the main ore shoot
was developed by two shafts 160 and 70 feet deep, respectively, these
being about 300 feet apart. The California State Mining Bureau Mines
Register for 1904 lists one shaft 100 feet deep and 300 feet of drifts.
In 1954, one partly caved shaft surmounted by a wooden head frame
could be identified. This apparently is the shallower of the two men-

there was no evidence of recent activity at the mine.
Gold Bug Mine. Location: Sees. 28, 33, T. 3 S., R. 17 E., M.D., in
Solomon Gulch 1 mile west of the Black Bart mine. Accessible by dirt
road from Date Flat on the Coulterville-Kinsey road via Dogtown and
Buckhorn Peak. Ownership : N. D. Madden and K. I. Goulder, c/o Bay
Construction Company, Ltd., Shelly Building, Vancouver, British
Columbia, own several unpatented claims.
The Gold Bug mine produced several thousand dollars worth of gold
from near-surface pockets in the 1880s and 1890s during the height of
mining activity in the Cat Town district. It was operated for a short
time in 1908 by Fred Shaw of Kinsey, in the late 1930s by N. D.
Madden and in 1940 under lease by S. S. Escobar. One ore shoot mined
between 1937 and 1940 contained 225 tons of ore which ran slightly
more than 3.5 oz. of gold and 0.75 oz. of silver per ton.
The vein roughly follows the contact between slate of the Paleozoic
Calaveras group, which forms the hanging wall side of the vein, and
massive greenstones of unknown age. The vein, which varies from a few
inches to several feet wide, is accompanied in places by albitite and
diorite dikes, similar to other mines in the Cat Town and Flyaway
Gulch district. According to Julihn and Horton (1940, p. 142) the
high-grade pockets tend to occur when the vein is entirely in slate and
where there is abundant calcite.
A 200-foot adit driven on the vein is the principal working. It pene-
trates the vein to a vertical depth of 70 feet. The ore shoot mined was
40 to 50 feet long, measured in the direction of strike of the vein, and
110 feet deep on the dip of the vein. In this shoot the ore averaged
more than $115 per ton (Julihn and Horton, 1940, p. 142).
Gold King (Martin-Walling , Sunshine) Mine. Location : Sec. 11,
T. 3 S., R. 17 E., M. D., in the Gentry Gulch district on the ridge crest
half a mile southwest of the Hasloe mine. Ownership : Russell G. Rowe,
Rt. 7, Box 1499, Modesto, California holds several claims adjoining the
Lovely Rodgers mine on the southeast.
The Gold King mine was discovered in the 1860s and was known
throughout its early history as the Martin-Walling or Martin and
Walling mine. Through the first few years of operation it was reported
to be fabulously rich. It was purchased in 1878 after some years of
idleness by Douglass and Stevenson who developed two ore shoots and
took out some ore. In 1879 it was reported sold by Joshua Hendy to
eastern people along with the Bondurant for $80,000 (Min. and Sci.
Press, vol. 39, no. 1, p. 5). By 1880 ownership had passed to P. P. Mast
who rehabilitated the 300-foot shaft and did considerable mining re-
sults of which have not been recorded. Some exploration and rehabili-
tation work was done on the mine under the name Gold King during
the 1930 's through an adit and raise below the old workings, but no
recent work has been done on it.
Two veins cross the property. The principal vein on which the main
shaft is sunk strikes roughly north and dips 36° east at the surface.
Poorly exposed at the surface, the vein appears to range from 2 to 4
feet wide. Vein matter is quartz with free gold, pyrite and tetrahedrite.
The second vein strikes more nearly to the northwest, dips 60-70° north-
Nos. 1 and 2] mines and mineral deposits, mariposa county 103
east and is separated from the main vein by about 200 feet of slate and
quartz-mica-graphite phyllite and schist. Vein matter is chiefly frac-
tured quartz and fractured wall rocks.
The main vein has been developed by an inclined shaft, sunk on the
vein, over 300 feet deep having' 2 levels. The shaft is equipped with
hoisting equipment and track but the mine is watered and partly caved
20 or 30 feet below the collar. No recent work has been done on it. The
west vein has been superficially developed by shallow shafts.
Golden Key (Austin) Group. Location: Sees. 29, 32, T. 4 S., R.
18 E., M.D., on Whitlock Creek 5 airline miles northwest of Mariposa.
Accessible from State Highway 49 by 5 miles of graded dirt road by
way of Whitlock and Sherlock Creeks.
Ownership : Golden Key Mining Company, c/o J. E. MacDonald,
Box 105D, Gilroy, California owns 6 patented claims, the Coronado
No. 2, Dusenberry, Golden Gate, Hayseed, Haywire Fraction and
Regan, and 3 mill sites.
Mining activity on the Golden Key claims dates back at least as far
as the 1880s. In the late 1880s and early 1890s the Hayseed mine and
the nearby Triumph and Farmers Hope (Miners Hope) mines were
being operated by J. B. Helm and Son and considerable specimen ore
was reported mined in 1890. In 1896 the Hayseed and Triumph claims
were sold by the Helms to Angus Mcintosh for $10,000 (Min. and Sci.
Press, vol. 62, no. 9, p. 204, 1896). About the same time H. C. Austin
of Fresno was operating the Regan mine from an 80-foot shaft (Storms,
1896, p. 222). By 1902 ownership of the Austin group of claims passed
to T. R. Lombard, Coronado, California, and A. M. Kitchen of Chicago,
and D. A. Connolly of San Francisco was named superintendent (Min.
and Sci. Press, vol. 85, no. 5, p. 64, 1902). In 1903 the Austin Group
Mining and Milling Company was organized with H. C. Austin as the
principal owner and W. H. Cavin as general manager. This company
intermittently operated various of the claims for more than 12 years.
William Dolph operated the Hayseed and Miners Hope claims for a
time in 1903 (Min. and Sci. Press, vol. 75, pp. 796, 944, 1903). Acquired
by the Golden Key Mining Company during the early 1920 's the mine
was intermittently operated by them until 1949. The properties have
been idle since 1949.
Two principal veins, the Regan and Hayseed, strike roughly north
and dip east, the Hayseed at 40° and the Regan at 65°. These crop out
about 50 feet apart and their surface courses are roughly parallel. The
Regan vein is believed to be the extension of the Miners Hope vein and
the Hayseed an extension of the Spread Eagle vein (Julihn and
Horton, 1940, p. 151). These veins are intersected approximately at
right angles by four lesser veins, the Golden Gate Nos. 1, 2 and 3 and
the Coronado No. 2. The cutter veins dip south at angles between 35°
and 40°. Much of the specimen ore taken from the mine has come from
the cutter veins but several good sized ore shoots have been developed
in the main veins. Wall rocks throughout the claims are meta-andesite
greenstone of unknown age.
According to Julihn and Horton (1940, p. 151) the Golden Key
group of claims had yielded $130,000 up to 1938 through a mined depth
of only 135 feet. Total recorded production to 1949 is estimated at more
than $154,000, but the production figures are difficult to check because
104 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
of the many different names under which production was reported.
The amount of gold produced before 1884 was not recorded. Ore pro-
duced between 1933 and 1949 apparently averaged about $12 per ton.
The highest grade ore from sustained mining was recorded in 1912-13
when 343 tons of ore yielded 600.33 oz. of gold and 39 oz. of silver
(U. S. Bureau of Mines records).
The principal workings on the Golden Key property are a long
crosscut adit called the Greenstone tunnel and the inclined Hayseed
shaft serving four levels. The Greenstone tunnel, more than 700 feet
long, was driven to intersect the cutter veins and ultimately to connect
with the workings from the Hayseed shaft. Its portal is close to the
Sherlock Creek road and it is driven approximately S. 80° W. across
the Golden Gate and Coronado claims. There are considerable drift and
slope workings from this tunnel. The Hayseed shaft, sunk on the
Hayseed claim and vein, has levels at vertical depths of 110, 220, 250
and 300 feet. More than 650 feet of drifts have been run from these
levels, mostly north of the shaft. On the 300-level south of the shaft
was an ore shoot 73 feet long and 5 feet wide in which ore averaged
$10-$12 per ton (Julihn and Horton, 1940, p. 151).
Near the south end of the Regan claim is a partly caved shaft re-
ported to be 310 feet deep. About 360 feet north of this shaft is the
Arndke shaft 80 feet deep, also caved, and there are two other caved
shafts on the Regan vein believed to be 190 and 110 feet deep, respec-
tively (Julihn and Horton, 1940, p. 151). The Greenstone tunnel was
the only working accessible to the authors in August 1954.
Granite King and Live Oak (Buckeye, Billings) Mine. Location:
SWi sec. 3 and NWi sec. 10, T. 6 S., R. 18 E., M.D., 3 miles south-
west of Mormon Bar and | of a mile south of the old Yosemite High-
way through Mormon Bar. Ownership : Edith McElligott, 1404 Poplar
Ave., Fresno, California, owns a patented property of 16 acres, parts of
the old Granite King and Live Oak claims.
The history of the Buckeye and Live Oak mine dates back beyond
1870. In 1871 rich ore from the upper, oxidized part of the vein was
being mined by a man named Hambleton (Min. and Sci. Press, vol. 23,
no. 16, p. 244, 1871). By 1902 ownership of the mine had passed to
the Krogh Manufacturing Company of San Francisco who sold the
property late that year to McCrae and Herman. (Min. and Sci. Press,
vol. 84, no. 14, p. 194, 1902). The Buckeye mine appears on the list of
mines of the Mariposa Commercial and Mining Company and appar-
ently was acquired by that company early in the 1900s. In 1909 the
mine was leased by John Hamm, C. P. Pratt and J. W. Pratt (Min.
and Sci. Press, vol. 92, no. 22, p. 732, 1904). These operators produced
22 tons of ore which yielded $174.52 or an average of $7.93 per ton
at the old price of gold (Logan, 1935, p. 188). By 1928 ownership had
passed to O. S. Evans of Hornitos (Laizure, 1928, p. 129) but little
or no mining was done in the 1920s. In 1938 the mine was reopened
a partnership of M. T. McElligott, Guy Noble and Howard Campbell
who operated the mine until 1941. During this period 9017 tons of ore
was milled which yielded 2295 oz. of gold and 916 oz. of silver or an
average of 0.243 oz. of gold per ton. The mine has been idle since 1941.
The main vein in the Granite King mine is 2 to 5 feet wide, strikes
N. 40° E. and dips 35° to 50° southeast. Wall rocks are coarse-grained

hornblende-biotite granodiorite and a finer-grained granitic dike rock
containing a greater proportion of dark minerals than the granodiorite.
According to Julihn and Horton (1940, p. 134), the dike intrudes the
vein fissure and in places has been brecciated and mingled with vein
matter. Ore minerals are native gold, auriferous pyrite, galena and
sphalerite in a milky quartz and brecciated wall-rock gangue. Milling
ore apparently averaged from 0.2 to 0.3 oz. of gold per ton with occa-
sional pockets of higher grade ore.
The principal workings are an inclined shaft at least 80 feet deep
and several hundred feet of drifts. Several vertical shafts in the vicin-
ity of the mill are flooded and of unknown depth. The main shaft is
equipped with a serviceable headframe, ore bins, hoist, skips and track.
It was flooded within 30 feet of the collar in September 1954 and there
was some caving below the collar.
The partly dismantled mill consists of a 16-inch jaw crusher, 4
stamps, amalgamating plates, a small ball mill and concentrating tables.
Repair shops and blacksmith shops are in good condition.

106 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
and Mining Company, c/o Eileen Milburn, Mariposa, California, owns
the remaining parts of the Las Mariposas Grant which was largely
liquidated in the early 1950s.
The Greens Gulch mine was well known through the early history of
Las Mariposas Grant and was probably discovered during the 1850s.
The principal periods of activity were in the 1860s and from 1901 to
1914. In the fall of 1941 the Green's Gulch mine, along with the Mt.
Ophir, Princeton, Louis Mt. View and Ortega, were optioned by J. K.
Wadley of Texarkana, Arkansas, and some exploration was done under
the direction of Charles Greenamayer. No work has been done on the
mine since 1941.
A typical Mother Lode mine, the Greens Gulch workings are on a
broad vein striking N. 50-55° W. and dipping steeply east. The main
vein is intersected by a northeast-trending cutter vein and much of
the ore apparently was at the intersection of these veins. The vein
matter is principally milky quartz containing native gold and aurifer-
ous pyrite. It locally contains quartz-ankerite-mariposite rock. The
Mother Lode in this area consists of a series of northwest-trending, en
echelon veins, rather than a single lode. The Greens Gulch vein is
probably an extension of the main vein at the Princeton mine. Wall
rocks are slate of the Upper Jurassic Mariposa formation.
Workings were caved and inaccessible in August 1954 but there is a
line of stopes, several shafts and tunnels. There must be extensive
drifts from the size of the dumps and the quantity of ore mined in
the early 1900s.
Mariposa Commercial and Mining Company records (1900-1915)
show that the Greens Gulch mine produced 10,625 tons of ore which
yielded $119,140.70 or an average value of $10.25 per ton at the former
price of gold. During the same period the Greens Gulch Extension pro-
duced 10.25 tons of ore from which $313.99 was realized, or an average
of $13.96 per ton. These figures indicate an average tenor of ore in
excess of half an ounce of gold per ton.
Hasloe (Funk, Coward, Hasloe and Centuary, Gentry Gulch) Mine.
Location: Sees. 1, 2, T. 3 S., R. 17 E., M.D., in Gentry Gulch 5£
airline miles southeast of Greeley Hill and 8 airline miles east of
Coulterville. Accessible by good dirt road from the surfaced Coulter-
ville-Greeley Hill road by way of Date Flat and Gentry Gulch. Own-
ership : Walter D. McLean, Joseph Dupret, Jr., Ralph J. Jacobs and
R. S. Hudgson, c/o Walter D. McLean, Coulterville, California, own
two patented claims of 41.12 acres and two unpatented claims.
The Hasloe mine was first located by Thomas Palmer in 1857 and
purchased that year by Samuel Funk. Samuel Funk was killed in a
mill accident about 1860. From 1860 to 1869 the property was success-
fully worked by H. G. Coward who completed the 5-stamp mill started
by Funk and increased it to 10 stamps. Then known as the Coward
mine, the ore consistently averaged $40 per ton and considerable speci-
men ore was taken out (Browne, 1868, p. 32; Min. and Sci. Press, vol.
26, no. 24, p. 373, 1823). In the fall of 1873 the mine was sold by
Coward to the Hasloe Mining Company and Robert Hannigan was
made superintendent (Min. and Sci. Press, vol. 26, no. 16, p. 245, 1873).
This company operated the mine until 1875 or 1876, finding several

high-grade ore shoots. Some work was done on the property late in
1877 and in 1878. The Mariposa Gazette, March 22, 1879 states that the
Hasloe had produced $800,000 to a depth of 300 feet. J. S. Morgan
and Sons took over the property about 1880 and operated the mine
until 1890. The mine is supposed to have produced over $3,000,000
under this management. After 5 years of inactivity the Hasloe was
reopened and during 1895 and 1896 produced 435.38 oz. of gold from
an unknown tonnage of ore. After a short period of inactivity an un-
successful attempt was made to reopen the mine in 1898. In 1909, or
1910 a company headed by H. P. Dalton of Alameda acquired the prop-
erty and it was operated by Hal G. Kennedy, Dalton 's brother-in-law,
until August 1911. A small tonnage of ore running 0.7 of an oz. of gold
was produced during this period. Gentry Gulch Consolidated Mines
Company had control of the Hasloe, Bandarita, Star and Texas Hill
mines in the late 1920s (Laizure, 1928, p. 88). The present owners
acquired the property in 1935 and operated it for two periods 1935-39
and 1942-48. It has been idle since 1948 and the workings below the
adit level are flooded, but the present owners were preparing to reopen
the mine in the summer of 1956.
Production of the Hasloe mine up to November 1, 1873 was reported
in the Mining and Scientific Press (vol. 27, no. 20, p. 309) to be
$200,000, but a previous issue of the Mariposa Gazette places the pro-
108 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
duction at $600,000 up to 1866. No records are available for the period
1874 to 1910 but there was a substantial production of high-grade ore
in 1874-75-76. According to U. S. Bureau of Mines records 3284 tons
of ore was taken from the mine between 1910 and 1948 from which
1703.68 oz. of gold and 232 oz. of silver were extracted, or slightly more
than $30,000.
The Hasloe vein averages about 30 inches wide but locally is as nar-
row as 6 inches and as wide as 5 feet. At the surface the vein strikes
N. 50° W., and does not deviate more than 5° over a distance of 850
feet. It dips 28-30° northeast. Vein matter is milky quartz mingled
with wall-rock gouge and in places ribboned by parallel inclusions of
slate. Ore minerals are native gold, tetrahedrite and a little galena and
arsenopyrite. Tetrahedrite is commonly associated with concentrations
of gold and is believed to be an indicator of good ore. According to
Browne (1868, p. 32) two ore shoots were developed during the early
years of mining. These were about 100 feet long, pitched 40° east and
were worked to a depth of 170 feet. Ore shoots have averaged 0.5 and
0.6 oz. of gold per ton but occasional pockets of specimen ores were
found. Most of the gold occurs near the border of the vein, particularly
on the footwall side (Julihn and Horton, 1940, p. 139). Wall rocks
are principally slate and hornfelsic quartz-biotite rock derived from
shale and siltstone. A diorite dike has been intruded for 200 feet along
the vein fissure in the vicinity of the west ore shoot (Julihn and Hor-
ton, 1940, p. 139).
Principal workings on the Hasloe claim are a 500-foot inclined shaft
and a 700-foot drift adit. Most of the ore above the adit level has been
stoped. From the shaft there are 1750 feet of drifts on 6 levels. The
disposition of the workings may be seen in the accompanying diagram.

The Hite mine has been one of the most colorful and most productive
gold mines in Mariposa County, and the authors have attempted to
trace its history through old files of the Engineering and Mining Jour-
nal and Mining and Scientific Press. It was discovered in 1862 by John
R. Hite and made Hite a relatively rich man in the 17-year period
during which it was operated by Hite and Company. Development of
the mine was entirely by hand-methods, and arrastra milling. Hite was
able to get a small stamp-mill driven by water power into operation by
1866 and the capacity of the mill was doubled by 1868, The mine was
surveyed for patent in 1866. During the 17-year period of operation
by Hite and Company, Hite was the principal director of operations
although Peter Wynant was a partner with Hite for a short period in
the early 1860's. Under Hite's management, 2 long crosscut adits were
driven to the vein. The upper adit intersected the vein between 200
and 250 feet from the surface. The lower adit intersected the vein at

to the surface. The lower crosscut was the main means of entry during the later
years of operation. Diagram reproduced through courtesy of Francis H. Frederick.
a vertical depth of between 700 and 800 feet or an inclined depth of
over 900 feet. During the last few years of operations by Hite and
Company a winze or underground shaft was sunk from the end of the
lower adit to a depth of 330 feet and three drift levels were run from
this working.
In August 1879 the mine was sold by Hite for between $600,000 and
$650,000 to a corporation headed by W. S. Clark and J. R. Bothwell,
Hite remaining as a trustee in the new corporation. Considerable min-
ing and development was done by the company, particularly on work-
ings from the winze. Operation of the mine by this group ended in
1882 with a dispute and prolonged litigation. The litigation was not
settled until 1887. During that year the mine was reopened under
management of Judge Walker but the operation was short lived. In
1883 the mine was managed for a short time by the McCaw brothers.
In 1895, W. S. Chapman and associates organized the Hite Gold Min-
ing Company and the property was bonded to them for $100,000. This
venture also ended in litigation after minor production. A. H. Ward
and H. H. Todd purchased the Hite mine in 1899 for $46,000 and or-
ganized the Hite Cove Gold Mining Company. Little was accomplished
under this management. In 1903, Thomas Churchill of San Francisco
Nos. 1 and 2] mines and mineral deposits, mariposa county 111
purchased the property for an undisclosed sum and leased it to the
Arkell brothers. Early in 1905 the Yosemite Mining Company made
an unsuccessful attempt to open the Hite mine and later that year the
properties were purchased by W. M. Kirkhoff and associates of Min-
neapolis. The mine was active, apparently under lease, in 1909 and
1912 and some production was made during the latter year. By 1916,
ownership had passed to J. S. Spillman of San Francisco who held the
property until the late 1930s. About 1938 it was acquired by Minerals
Engineering Company of Los Angeles. This company did some work
but no production was recorded. In 1953-54 a road was cleared across
very difficult terrain from Incline almost to the mine and it may be
reopened in the near future.
The total production of the Hite mine has been estimated at various
figures between $2,750,000 and $3,000,000. (Min. and Sci. Press, vol. 81,
no. 10, p. 287 ; Julihn and Horton, 1940, p. 145) U. S. Bureau of Mines
figures show that about $55,000 in gold and silver was produced from
the mine between 1896 and 1912 but no precise figures are available
for the period 1862 to 1896. Published reports in the Mining and
Scientific Press show that $250,000 was realized during 1878 and simi-
lar amounts for several preceding years. A large percentage of the ore
mined prior to 1879 ran more than $40 per ton at the old price of gold.
The lowest grade of ore mined was taken out between 1904 and 1909
when 4625 tons of ore yielded 788.85 oz. of gold and 849 oz. of silver
or an average of only $3.68 per ton. In 1912 a small tonnage of ore was
mined which yielded nearly 3^ oz. of gold per ton.
At depth the Hite vein takes an almost straight course N. 70° W.
through the Priest and Coleman, Hite and Giltner claims, and dips
75° to 80° north. Through the Hite Central claim, which adjoins the
Giltner on the southeast, the strike of the vein swings to about N. 50°
W. At the surface and to a depth of 600 feet on the Hite claim, the Hite
vein splits into two branches separated by a lenticular horse of slate
and schist 600 feet long and 50 feet thick at the thickest place. Vein
matter in the two parts of the Hite vein varies from a few feet to more
than 12 feet. Along the borders of the slate-schist horse the vein is 25
feet thick (Storms, 1894, p. 170).
A second vein striking N. 60°-70° W. and also dipping steeply
north traverses the McConley and Old Dominion claims. Where ob-
served this vein was 2-5 feet thick. A third vein striking about N. 10°
E. and essentially vertical crosses the Summit claim.
The vein fissures cut metasedimentary rocks of the Paleozoic Cala-
veras group. Dark slate, graphitic schist, quartzite, metasandstone and
dense, massive quartz-biotite hornfels are the principal wall rock types.
Bedding, where discernible, is parallel to the schistosity and cleavage,
has a general strike of N. 50° W. and dip of 75°-80° NE. The meta-
sediments are cut by a variety of small dikes and sills of granitic
rocks ranging in character from white aplite to dark biotite-hornblende
granodiorite.
Inasmuch as most of the veins of the Hites Cove district crop out
on the south slope of a steep, west-trending ridge, they have been
developed almost exclusively by crosscut adits connecting with drift-
levels. There are several relatively short adits on the McConley and Old
Dominion claims but the principal workings are the two long adits on
112 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
the Hite claim driven by Hite. The upper adit is 720 feet long, and has
east drifts reaching to the Hite Central claims and west drifts for an
unknown distance. The lower adit, a little more than 500 feet below
and almost due south of the upper level, is 1400 feet long. It has several
thousand feet of drifts on the adit level. At the end of this adit is a
winze or underground shaft 330 feet deep with 3 levels, presumably
100 feet apart. The Mining and Scientific Press (vol. 58, no. 26, p. 611,
1894) mentions east and west drifts from the bottom of the inclined
winze and a crosscut and drift driven from the footwall branch of the
vein into the 14-foot wide hanging wall branch of the vein from the
end of the east drift. Very little other work had been done on the
hanging wall branch of the Hite vein up to 1895 but the ore apparently
was of considerably lower grade than in the hanging wall side. In
various places, on the lowest level the footwall vein apparently pinches
out and no effort was made to follow it deeper. Most of the ore in the
footwall branch of the vein above the lower adit probably has been
stoped out but records are fragmentary.
Horseshoe (Bower Cave) Mine. Location: NE J, sec. 23, T. 2 S., R.
17 E., M.D., on the southwest side of Jordon Creek f of a mile north-
west of Bower Cave or 8 airline miles northeast of Coulterville. Acces-
sible via the Greeley Hill-Smith Creek-Bower Cave road from Coulter-
ville, a distance of about 13 miles. The road is paved as far as Dudley
Hill. Ownership: Joseph Dupret Jr. and Irene Dupret, Star Route,
Box 21B, Cazadero, California, own one patented claim of 20 acres.
Walter D. McLean of Coulterville is mine manager.
The Horseshoe mine, known in early days as the Bower Cave mine,
was discovered about 1867 probably by Andrew Rocca. In 1879 it was
sold by a Dr. Austin to P. P. Mast who was operating the Bandarita
and Martin Walling mines. Most of the early work on the mine was
done by Mast between 1879 and 1881. Ore was milled at the Martin-
Walling mill (Min. and Sci. Press, vol. 39, no. 26, p. 413, 1879; vol.
43, pp. 236, 252, 1881). By 1904 ownership of the mine had passed to
Rodgers and Loomis of Springfield, Ohio (Aubery, 04, p. 11). Some
work was done on the mine in 1910 by Francis B. Loomis. In 1913
the mine was bonded to T. G. Mudgett of San Francisco but no produc-
tion was recorded. In July 1951 the present owners reopened the mine
and it was put into active operation in November 1953. Since 1951 the
mine has produced $13,800 almost entirely from development work.
There are two nearly parallel veins on the Horseshoe claim striking
N. 68°-72° E. and dipping 65° SE. to vertical. The north vein, approxi-
mately 40-70 feet from the south vein, varies from a few inches to 16
inches wide and the south vein varies from 2 to 4 feet wide. Wall rocks
are graphitic slate and hornfelsic quartz-biotite-graphite rock derived
from clay shale and siltstone. Cleavage in the metasedimentary series
strikes NW and dips SW. Vein matter consists chiefly of bluish to
milky quartz, commonly ribboned with thin sheets of slate, and wall
rock gouge. Ore minerals are native gold, pyrite, chalcopyrite, arseno-
pyrite, galena and sphalerite. Millheads assay from $30 to $50 per ton
in gold.
The principal workings consist of a crosscut adit about 200 feet long,
which intersects the north vein at a depth of about 125 feet, 1500 feet
Nos. 1 and 2] mines and mineral deposits, mariposa county 113
of drifts and secondary crosscuts from the adit level, and an under-
grbund vertical shaft or winze now being sunk on the south vein at its
intersection with the crosscut. In August 1955 this shaft was down 50
feet and had 130 feet of drifts on the one sub-level.
The ore is hand-trammed from the mine to a 20-ton ore bin, passed
through a jaw crusher and Huntington mill. It is ground to pass a 40-
mesh screen before being passed over amalgamation plates and con-
centrating tables and sent through flotation cells. Sponge gold is sent
to the mint and the sulfide concentrate to the Selby, California, smelter.
Three men operate the mine and mill. Six tons of ore are processed per
day.
Independence (Twin Springs) Mine. Location: NE J sec. 23, T.
3 S., R. 18 E., M.D., on the Jenkins Hill road half a mile (airline) east
of the Briceburg-Kinsley road but about 3J miles from the Briceburg
road via the unimproved Jenkins Hill road. Ownership: Charles Jor-
dan, 633 Green Ave., San Bruno, California owns one unpatented
claim of about 20 acres, but ownership was disputed in August 1955
by other individuals.
The authors were unable to gather any information on the early
history of this property. At the time it was reactivated under lease
by Delaney and Rohrback in 1934 the workings were extensive. One
shoot mined between 1932 and 1934 ran between $80 and $140 per
ton (George Matlock, personal communication, 1955). The claim is op-
erated intermittently by the listed owner and by other individuals who
also claim ownership.
The Independence vein strikes N. 55° W., dips 75-80° NE. and
averages about 18 inches wide. Vein matter is ribbon quartz with
pyrite, galena, and native gold. Wall rocks are slate and schist of the
Paleozoic Calaveras group intruded by granitic dikes. The dikes com-
monly are schistose and well altered.
The principal working is a crosscut adit 300 feet long driven north-
east to the vein and striking it 50 to 60 feet below the surface outcrop.
From the end of the crosscut a drift has been run about 200 feet north-
west and 100 feet southeast developing 300 feet of backs averaging at
least 50 feet high. Much of the vein between the crosscut and the sur-
face has been stoped, but no work has been done below the crosscut
level.
Iron Duke Mine. Location : NWi sec. 4, T. 4 S., S. 16 E., SWJ sec.
33, 3 S., 16 E., M.D., in the northwestern part of Hunter Valley about
5 miles by paved and graded dirt road from the intersection of the paved
Bear Valley-Hornitos road. Ownership : Mrs. Louise M. Broad, 3469
Twentieth St., San Francisco, California, owns five unpatented claims,
the Iron Duke, Commercial, Pedro, Protection and Protection No. 1.
The Iron Duke mine was discovered prior to 1865, probably about the
same time as the Oakes and Reese mine, which adjoins it on the north-
west. During the early history of operations a 100-foot shaft was sunk
at the junction of the principal Blue Lead vein and an intersecting
cutter vein. During the sinking of the shaft a small pocket of ore was
found which yielded 190 oz. of gold (Julihn and Horton, 1940, p. 119).
The property was worked from time to time by lessees but the principal
periods of exploration were 1934-35 under E. F. McTarnahan and 1938-
114 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
41 under J. 0. Gillice. It has been idle, except for assessment work, since
1940. In July 1954 the underground workings were inaccessible because
of flooding. There was no headframe but a hoist house, compressor
house, blacksmith shop, mill building, watchman's cabin and some mill-
ing equipment were on the property.
The Iron Duke claim is oriented on the Blue Lead which passes
through the adjoining Iron Duke and Carson mines as well as several
others in the district. This vein strikes N. 30-35° W., dips east at an av-
erage of 61°, averages 4 feet wide, and is traceable for 1500 feet (the
entire length of the claim). It is joined at angles between 45° and 90°
by a series of cutter veins spaced about 250 feet apart. These enter the
Blue Lead from the west but do not cross it (Gillice, J. O., private re-
port). Most of the ore has been taken where the cutter veins join the
Blue Lead or from the cutter veins themselves, but some small ore shoots
have been found in the Blue Lead on the adjoining Oakes and Reese
property. The two Protection claims and the Commercial claim cover
extensions of the cutter veins followed west from the Iron Duke claim.
Several of the cutter veins have been traced west of the Blue Lead for
more than 600 feet.
The Blue Lead follows a fissure which in general lies between basalt
and andesite greenstone on the west and tuffaceous slate and chert on
the east. The cutter veins are found entirely in greenstone. The wall
rocks are part of the Upper Jurassic Amador group (Taliaferro, 1943,
pp. 282-284) which is predominantly a volcanic assemblage.
The principal working is single compartment and manway shaft 200
feet deep inclined 61°. At the 185-foot level a drift was run south 500
feet to Cutter Vein No. 2 and a secondary drift was driven west 100
feet on Cutter No. 2. This secondary drift encountered an ore shoot
and a 30-foot raise was driven, but no stoping was done (Gillice, J. O.,
private report, p. 6). One powder box full of ore taken from a pocket
in this shoot yielded $524. The main drift was continued south to the
junction point with Cutter Vein No. 3 and a 75-foot drift was run west
on that secondary vein (Julihn and Horton, 1940, p. 119). In addition
to the main workings there is a partly caved 35-foot shaft and numerous
shallow surface workings in the vicinity of Specimen Hill on the Iron
Duke claim.
According to Gillice (private report) $16,000 in gold was taken from
shallow workings on Specimen Hill, $3800 was taken from a small stope
at the junction of the Blue Lead and Cutter Vein No. 1 at a depth of
104 feet, and $2000 was recovered during driving of the raise on Cutter
Vein No. 2. U. S. Bureau of Mines records indicate a gold production
of $2000 for the period 1932-1941. Except for occasional pockets of
bonanza rock the average milling ore runs about $10 per ton at a gold
price of $35 per oz. Sulfide concentrates, chiefly marcasite and arseno-
pyrite, rarely contain more than $50 per ton (Julihn and Horton, 1940,
p. 119).
Jumper (Jumper and Bear) Mine. Location: N| sec. 30, T. 4 S.,
R. 17 E., M.D., on top of Bear Valley Mountain 2 -J airline miles west of
Bear Valley. Accessible via 1 mile of unimproved dirt road from the
surfaced Bear Valley-Hornitos road. Ownership : Not determined. Last
operator was C. H. Burt of Bear Valley. Property originally consisted
Nos. 1 and 2] mines and mineral deposits, mariposa county 115
of two claims, the Jumper and Cold Springs or Bear embracing about
35 acres.
The Jumper mine was discovered in the 1850s, worked intermittently
to 1917 and almost continuously in a small way from 1917 to 1937. Ore,
though not present in large shoots, ran from ^ to 1 oz. of gold per ton!
Most of the work from 1917 to 1940 was done by C. H. Burt of Bear
Valley. There has been no recorded production from the mine since
1940.
According to Laizure (1928, p. 91) there are two nearly flat, lam-
inated quartz veins one above the other, varying from a few inches to
more than 4 feet wide which carry very finely divided native gold. These
apparently strike N. 75-80° E. but are well obscured by soil mantle. The
lowest mill run made in the late 1920s gave a recovery of $19 per ton
at a gold price of $20.67 per oz. Production records for the period
1925-28 show a yield of nearly 1 oz. of gold per ton. Between 1919 and
1922 over 621 oz. of gold and 75 oz. of silver was obtained from only
43 tons of ore.
In September 1954, there were 3 inclined shafts less than 100 feet
apart watered and partly filled with debris. One of these is at least 180
feet deep (Laizure, 1928, p. 91). There are also two vertical shafts open
to a depth of at least 100 feet, three other caved shafts and numerous
partly caved stopes and open cuts. There was a small Gibson mill and
a steam engine on the property when it was last visited in 1954.
Juniper (Juniper and Patricia, Patricia and Charles) Mine. Loca-
tion: SWi sec. 19 and NWi sec. 30, T. 4 S., R. 17 E., on Bear Valley
Mountain 2^ miles west of Bear Valley. Accessible via half a mile of
unimproved dirt road from the surfaced Bear Valley-Hornitos road.
Ownership: Pereno O. Zirker, Pearl Crowell, Ella B. Edwards and Hal-
lett B. Hammatt, 832 Franklin St., Monterey, California own a patented
claim of 20 acres and several unpatented claims. The property originally
included the Juniper, Independence, Starlight (Patricia) and Mt. View
lode claims and the Independencio placer claim. One of these claims
apparently was renamed the Charles.
As nearly as can be determined from meager early records, the Ju-
niper group of claims was probably first located in the 1850s about the
same time as the adjacent Jumper mine. The mine was known to be
active in 1882 with Stephen Arthur as superintendent and Samuel C.
Bates as principal owner (Min. and Sci. Press, vol. 45, no. 12, p. 180,
1882). Later C. C. Schlageter of Mariposa came into possession of part
of the claims and others were acquired by the Zirker family. The last
period of operation was 1933-37 when both properties were leased by
George L. Reed of Bear Valley and worked under the direction of War-
ren Dutton and D. R. Jones. There has been no apparent recent activity
at the mine.
There are two sets of veins in the Juniper group of claims. The veins
on the Juniper and old Mountain View claims strike roughly north but
are somewhat sinuous and dip east and angles between 45° and 60°.
Those on the Starlight (Patricia) and Independence claims strike gen-
erally northwest but are somewhat arcuate and dip northeast at angles
similar to those of the other vein system. Some vein offshoots from the
north-trending system strike east of north and tend to be steeper than
the main veins. Vein widths vary from 1 foot to 5 feet. Wall rocks are
116 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
massive and schistose greenstone derived from pyroxene andesite. They
are of Upper Jurassic age.
The Juniper vein is opened by an adit level 500 feet long which
reaches a vertical depth on the vein of 130 feet at the south end. There
are several partly caved stopes or airshafts from this level to the sur-
face giving a total footage of workings of about 800 feet (Laizure,
1935, p. 34). On the Starlight or Patricia claim there is a 320-foot
vertical shaft with several hundred feet of drifts. These workings were
partly caved and inaccessible in August 1955.
Data on the production of the mine is incomplete but the total ton-
nage of ore is relatively small. At least 1000 tons were milled between
1919 and 1940 with returns running from 14.4 oz. of gold and 4 oz. of
silver per ton to 0.35 oz. of gold per ton. The average tenor of ore was
about 1.04 oz. of gold and a fraction of an ounce of silver per ton.
Lafayette and Lafayette Extension (Ghirardelli) Mine. Location:
Sec. 15, T. S., R. 16 E., M. D. near the south end of Hunter Valley
west of the paved Hunter Valley road and f of a mile north of the
Pyramid mine. Ownership : Louis and Gabriel Queriolo, 861 San Ramon
Way, Sacramento 21, California, owns two claims, part of a parcel of
patented argicultural land.
The Lafayette mine is an old property active chiefly in 1866-67. In
1866 it was being operated by a San Francisco group headed by
Samuel Miller with H. C. Treon as superintendent (Min. and Sci. Press,
vol. 12, no. 18, p. 274, 1886). Late that year an inclined shaft had been
sunk to a depth of 90 feet and a vertical shaft 70 feet deep. A 4-stamp
mill was in operation. The ore yielded $25-$30 per ton. By 1867 owner-
ship had passed to D. Ghirardelli of Oakland. The vein varied from 1
foot to 3 feet thick and was yielding $30-$40 per ton (Min. and Sci.
Press, vol. 15, no. 15, p. 69, 1867; vol. 17, no. 3, p. 38, 1868). By 1920
ownership of the property had passed to Dr. C. A. Queriolo of Oak-
land and has remained in the Queriolo family to the present.
The Lafayette vein is narrow but ore shoots have been consistently
of good grade. It strikes north and dips east at about 40°. The vein
fissure has developed along or close to the contact of pyroxene andesite
greenstone of the Logtown Ridge member of the Upper Jurassic Ama-
dor group and laminated tuffaceous sediments of the Hunter Valley
chert member of the same group (Taliaferro, 1943, pp. 282-284).
Workings are inaccessible and there has been no recent work done on
the mine.
Ljandrum (Barley Field) Simeon Landrum Mine. Location: Sees.
27, 34, T. 4 S., R. 18 E., M.D., 1 mile south of Colorado School just west
of the Colorado-Sherlock Creek road and 5J airline miles northeast of
Mariposa. Ownership : George Matlock, Mariposa, California, owns the
Old Standby claim containing 20 acres, surveyed but not yet patented.
The Landrum or Barley Field mine was discovered sometime prior
to 1889, probably by Joseph Landrum. In 1899 it apparently was op-
erated in conjunction with the Champion mine by a partnership of
James Ridgway, Colonel Dunbar and Mr. 'Hay (see Champion II mine).
The property originally consisted of 3 claims including the Simeon
Landrum and Old Standby, but the others apparently were abandoned
prior to 1928 when the property passed to Harry I. Maddox of Merced.
Nos. 1 and 2] mines and mineral deposits, mariposa county 117
Most of the production of the mine was never recorded, but from 1897
to 1905 about 250 oz. of gold was produced from an unknown tonnage
of ore (U. S. Bureau of Mines records). Some shallow exploratory
work is done from time to time by the present owner but underground
workings are difficult to support and the rather extensive old workings
cannot be entered. The mine is characterized by pockets of very rich
ore which are in places found in vein quartz and in others in dis-
integrated dike material.
The main Landrum vein of brecciated milky quartz strikes N. 35-40°
W., dips 45° SW. and averages 2-4 feet wide. It is accompanied over
much of its length by a clayey, much altered dike, mineralized in part,
so that the ore-bearing zone is, in places, over 10 feet wide. Wall rocks
are hornblende-biotite granodiorite and finer-grained feldspar por-
phyries. A second vein crops out 50-60 feet southwest of the main vein
and roughly parallel thereto. In the few places it is exposed it is 4-5 feet
wide and dips 50 to 65 degrees southwest. About 400 feet northwest
of the end-line of the Old Standby claim and slightly en echelon to the
Landrum vein is a 2-foot wide vein of bluish, glassy quartz carrying
abundant chalcopyrite.
In the 1920 's there was 90-foot shaft serving over 800 feet of drifts.
In September 1955 these workings had been almost obliterated but the
course of the vein is marked by a long series of shallow open cuts some
of which may once have been stopes. All of the present work is done
from shallow open workings. Owing to the softness of the vein and sur-
rounding rock open-cut mining by steam shovel might be feasible in
the dry season.
Live Oak and Governor (Stud Horse Flat group. Live Oak group,
White Oak group) Mines. Location: Sec. 35, T. 3 S., R. 16 E., M. D.
on the south side of Merced River Canyon 2 miles northwest of Bagby.
Accessible by 3^ miles of jeep and foot trail from the Schoolhouse mine
on the paved Hunter Valley Road. Ownership : North American Gold
Mines, Inc., c/o Ada Stewart, 25 Delmar Ave., San Jose, California
owns a group of unpatented claims and several mill sites, notably the
Live Oak, Governor, Red Oak, Monitor, Grand View, Henrietta, Lincoln
and Roosevelt claims.
Originally known as the Stud Horse Flat group of mines, the Live
Oak and Governor probably were discovered in the 1890s or early 1900s.
A 3-stamp mill, one of the early installations at the mines, burned in
1907 (Castello, 1921, p. 139). The first owner of record is John P.
Carroll of Bagby who intermittently operated the property from about
1910 to the late 1930s. In 1914 workings consisted of a 140-foot shaft
with two levels, 300 feet of drifts and a stope 250 feet long and 60 feet
high; also several shallow shafts and short tunnels (Lowell, 1916, p.
598). The property was bonded for a short period in 1918 to a Los
Angeles company, but no production was recorded (Castello, 1921, p.
139) and a 5-stamp mill brought on to the property was never erected.
During the 1920s John Carroll ran a 225-foot crosscut adit southwest
to the vein cutting it at a depth of 68 feet. From this crosscut a 250-
foot southeast drift was run, a winze put down 20 feet and a raise put
up to the surface (Laizure, 1928, p. 95). During the early 1930s a 250-
foot double compartment shaft was sunk 25 feet southeast of the cross-
cut adit, the drift from the 68 or adit level was lengthened to 322 feet
118 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
and drifts on the 225-foot level were run 250 feet northwest and 250-
feet southeast of the shaft. There has been little activity at the mine
other than assessment work since 1938.
The Live Oak vein strikes northwest and dips about 75° southwest.
It can be followed at the surface for more than a mile, averages 3-4
feet wide and reaches a maximum width of 10 feet. A smaller cutter
vein, the Roosevelt, intersects the main vein crossing the Roosevelt and
Lincoln claims. Vein matter is milky quartz with native gold, galena,
and pyrite. Wall rocks are pyroxene andesite greenstones of the Pefion
Blanco member of the Upper Jurassic Amador group (Taliaferro, 1943,
pp. 282-284). The greenstones contact the Mariposa slate about half a
mile east of the mine.
Most of the workings have been described previously. The two shafts
on the Live Oak claim are 212 feet apart, the more southerly caved
above the 68-foot level, but the main (northerly) shaft in good condi-
tion. On the Governor claim are two adits, a lower, 112 feet long, and a
second one 50 feet higher, 20 feet long with a 10-foot winze near the
end (Julihn and Horton, 1940, p. 128).
The Carrolls estimated in 1932 that there was 14,000 tons of ore
between the 68-foot and 225-foot levels from the main shaft that would
average $10.50 per ton. There is no record of any of this having been
removed, but recorded production from the mine between 1931 and
1934 indicated that some ore ran considerably less than $10.50 per ton.
(U. S. Bureau of Mines records) Some sampling data are included in
accounts by Julihn and Horton and Laizure, references previously

production from the Live Oak and Governor group of mines.
Long Mary Mine. Location: Sec. 17, T. 5 S., R. 17 E., M.D., J of a
mile north of the Mount Bullion-Hornitos road and 6 miles by paved
road west of Mount Bullion. Ownership : Not determined. Most of the
land in this area has reverted to agricultural status. Property was for
many years a part of the holdings of the Mariposa Commercial and
Mining Company.
The Long Mary mine has a long history dating back prior to 1900.
Most of the recorded activity has been by lessees working with the
management of Las Mariposas Grant. The principal periods of activity
were 1900-1905 ; 1908-11 and 1914-1915. During this span of time the
mine produced 9348.9 tons of ore which yielded $108,928.44 or an
average of $11.65 per ton at the old price of gold. (Logan, 1935, p. 188)
The entire surface installations including a 5-stamp mill were destroyed
by a forest fire in 1927 (Laizure, 1928, p. 95). In 1939 an option to
purchase the Long Mary and several other prominent Las Mariposas
Grant mines was granted to the San Rosario Mining Company headed
by A. R. Gordon of Washington, D. C, but the deal was never consum-
mated. (Eng. and Min. Jour., vol. 140, no. 7, p. 62, 1939). There has
been no production from the mine since 1915 and the workings are
inaccessible.
The Long Mary vein strikes N. 85° W., dips 65° south and averages
about 2 feet wide. Wall rocks are slate of the Upper Jurassic Mariposa
formation. Vein matter is milky quartz with native gold and pyrite.
The principal ore shoot was 350 feet long and at least 400 feet deep,

judging from the shape of the stopes reported by Castello (1921 o
121).
In 1920, the workings consisted of a 413-foot inclined shaft with
4 levels and an adit 263 feet long. There were 360 feet of drifts on the
200-level, 383 feet on the 300-level, 315 feet on the 350-level and 163
feet on the 400-level plus 900 feet of raises and a stoped area 400 feet
high and 350 feet long (Castello, 1921, p. 121),
Louis and Louis Extension Mines. Location: Sec. 11, 5S., 17E.,
M.D., half a mile southwest of the Mt. Opher Mint historical marker on
Highway 49. Adjoins the Mountain View mine on the southeast and
is half mile northwest of the Greens Gulch mine. Ownership : Mariposa
Commercial and Mining Company, c/o Eileen Milburn, Mariposa,
California owns a parcel of land containing 240 acres that includes the
Mt. View, Louis, and Louis Extension mines.
The Louis and Louis Extension are adjoining claims, on a con-
spicuous quartz vein of the Mother Lode system and probably were
first opened up in the 1850s. Throughout its history it has been oper-
ated principally under lease from the management of the Mariposa
Grant, most notably from the Mariposa Commercial and Mining Com-
pany. The principal periods of activity have been 1900-1903, 1905-06,
and 1912. In this period the Louis claim produced 1240.14 tons of ore
from which gold worth $27,691.33 was extracted or an average of
$22.36 per ton at the former price of gold. The Louis Extension, last
active in 1912, produced 10 tons of ore yielding $141.42 or $14.14 per
ton (Logan, 1935, p. 188).
Through the Louis and Louis Extension claims the main vein strikes
approximately N. 62° W. and dips 55° NE. As it reaches the Mt. View
claim farther to the northwest the strike changes to about N. 47° W.
According to Lowell (1916, p. 586) the vein exposed in the workings
averages 4 feet wide. At the surface much of it is obscured by mantle.
Wall rock is black slate belonging to the Upper Jurassic Mariposa
formation. Vein matter is chiefly milky quartz containing native gold.
According to Castello (1921, p. 121) the sulfide content is low. Castello
mentions a second, presumably parallel, quartz vein also 4 feet wide
but lists no further details. This could be any of several veins in the
vicinity.
In 1920, the workings included a vertical shaft 375 feet deep with
three levels at 100-foot intervals, several crosscuts and winzes and a
150-foot air shaft. There were 275 feet of drifts on the 100-level, 75
feet on the 200-level and 500 feet on the 300-level. Crosscuts totaled 775
feet and winzes 600 feet. None of the workings were accessible in
September 1954. The site of the main shaft is marked by a large white
dump.
Louisa (Louise, Louise Point) Mine. Location: Sec. 3, T. 3 S., R.
16 E., M.D., astride State Highway 49, \ of a mile south of Coulter-
ville. Ownership : Walter J. Lautenschlager, 626 South Catalina St.,
Los Angeles 5, California, owns a patented property of 25.29 acres.
The Louisa mine is typical of the Mother Lode mines in northern
Mariposa County. The prominent, massive, milky quartz reef and ac-
companying quartz-mariposite-ankerite vein matter crossing Highway
49 just below Coulterville make well-known landmarks in the southern
120 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
part of the gold belt. Early records of the mine have been lost but it
undoubtedly was one of the first claims to be located in the 1850s, the
vein system being the most conspicuous in the Coulterville district
short of the Penon Blanco itself. The principal period of activity at
the mine was 1894-1900 when the Merced Gold Mining Company, J. R.
Gilbert, superintendent, spent more than $56,000 in improvements and
development work (Eng. and Min. Jour., vol. 61, no. 3, p. 68, 1896).
Milling was done at the Potosi mill 1J miles to the west. Prior to
acquisition of the mine by Merced Gold Mining Company the property
was part of the 20,000 acre Cook Estate. A General Boyd of San Fran-
cisco owned the property for a short period about 1893-94 (Storms,
1896, p. 172). There has been no sustained work on the mine since
1900. No equipment is on the property and the workings are inac-
cessible.
The east branch of the Mother Lode passing the length of the Louisa
claim is a broad, multiple vein more than 300 feet wide striking N.
40-45° W. and dipping 70-75° NE. The bulk of the vein consists of
quartz-mariposite-ankerite rock derived in considerable part from hy-
drothermal alteration of serpentine. Several tabular to lenticular sheets
of massive, milky quartz traverse the quartz-mariposite-ankerite rock
in sub-parallel or braided fashion and the adjoining masses of vein
matter are interlaced by stringers of milky quartz. In the upper, oxi-
dized parts of the vein system the quartz-mariposite-ankerite rock has
been converted to a spongy, rust-colored, earthy rock consisting chiefly
of yellow oxides of iron intermixed with quartz stringers. Ore shoots
of native gold and auriferous pyrite commonly are large but of rela-
tively low grade. They generally are found in quartz-mariposite-anker-
ite rock on the hanging wall or footwall side of the massive quartz sub-
veins. The bulk of ore produced ran less than $12 per ton at the former
price of gold. According to Storms (1896, p. 172) when the vein matter
was solid mariposite-ankerite rock without quartz or a brecciated ap-
pearance the gold content in the ore was too small to pay.
The vein system in the east branch of the Mother Lode lies along the
contact of black slates of the Upper Jurassic Mariposa formation and
massive pyroxene andesite greenstone probably belonging to the Penon
Blanco member of the predominantly volcanic Amador group, also of
Upper Jurassic age. A good sketch of the vein system, as seen in plan,
has been drawn by Storms (1896, p. 172). The rock marked diabase
on the sketch is greenstone derived from pyroxene andesite.
In 1900, workings consisted of the vertical Nelson shaft 375 feet deep
with 3 levels and an air shaft 150 feet deep. There were 275 feet of
drifts on the 100-level, 75 feet on the 200-level and 500 feet on the
300-level, plus crosscuts totaling 775 feet and winzes totaling 600 feet
(Laizure, 1928, p. 96).
Louisiana Mine. Location: Sees. 25, 26, T. 2 S., R. 17 E., 12 miles

Discovery of the Louisiana mine was probably made in the early
1860s. In January 1866 the mine was purchased and placed in opera-
tion by the Heslep family (Min. and Sci. Press, vol. 12, no. 3, p. 40,
1866). Judge Heslep, W. C. Heslep and his son P. C. Heslep operated
the property until the spring of 1867. During- this period ore ran from
$10 to $50 per ton plus the yield of a sulfide concentrate not readily
reduced which assayed $100 to $500 per ton. Some interesting; machin-
ery was installed by the Hesleps and their predecessors including two
mechanically driven sledge hammers made by Rex, Logan and Com-
pany, a walking-beam type of pumping engine (English-made) and a
Hogan de-sulfurizing furnace burning hydrogen gas. The sulfide con-
centrates could be handled in this furnace for $1 per ton (Min. and Sci.
Press, vol. 12, no. 3, p. 40, 1866). At the time the Hesleps took over
the mine there was a crosscut tunnel 200 feet long cutting the vein
at a depth of 100 feet and a connecting shaft from the surface. In the
spring* of 1867 management passed into the hands of Colonel Conley,
terminating a short layoff. The Louisiana claim was patented in Feb-
ruary 9, 1878 (Julihn and Horton, 1940, p. 136) and was active at
least intermittently through the 1870s and 1880s. About 1891 three
additional shafts were sunk and a 4-stamp mill installed. A. C. Cable
superintended operations for J. J. Grove of San Francisco at the mine
in 1896 (Min. and Sci. Press, vol. 73, no. 12, p. 242, 1896). In 1898 the
owners gave up operation of the mine but it was leased for a short pe-
riod bv former employees who took out 600 or 700 tons of ore which
yielded $10,330.98 (Julihn and Horton, 1940, p. 136). In 1911 the prop-
erty was bonded to G. F. Dyer of Merced who apparently did some
exploration and development work but no mining. By 1920 ownership
of the mine had passed to C. P. Treat and the mine was put under
option by A. T. Adams of the Bondurant mine (Castello, 1921, p. 126),
but final sale was not consummated. The mine has remained in the
Treat family since that time. In 1953 and 1954 some work was done
on the north end of the claim by E. W. Ferguson of Coulterville.
Massive white quartz of the Louisiana vein is boldly exposed at the
crest of a low ridge north of the road through the Bondurant property.
It strikes N. 70° W., dips 55° NE. and ranges from 2 feet to more
than 15 feet wide. The southwest or hanging* wall side of the vein
consists mainly of massive milky quartz in which gold values are low.
The best ore apparently is concentrated in the 3- to 6-foot wide part
of the vein nearest the footwall (Julihn and Horton, 1940, p. 137).
The best grade of ore apparently came from the southeast half of the
claim, judging from the concentration of workings there. Vein matter
in the ore shoots consists of native gold, galena, sphalerite and pyrite,
pyrite being most abundant. Julihn and Horton (op. cit.) stated that
the ore would probably average 1| to 2J percent sulfides. Wall rocks
are mainly black slate and graphitic mica schist, metasediments belong-
ing to the Paleozoic Calaveras group. The vein is accompanied over
part of its length by a badly altered ochrous granitic rock. According
to Julihn and Horton the vein contains ore for more than 1200 feet
of strike length, principally on the hanging wall side. Samples ran
from $6 to $15 per ton, presumably at the present price of gold. The
mine production figures have not been recorded.
122 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
There are five shafts of various depths on the propert}- exclusive of
the one started recently on the hanging wall side of the vein near the
north end of the claim. The Number 2 shaft is reported to be 250 feet
deep and the No. 3 shaft 150 feet deep (Julihn and Horton, 1940, p.
138). The various shafts could not be distinguished one from the other
at the time of the authors' visit in 1954. There are 2 tunnels on the
northwest part of the claim which could easily be cleaned out and an
undetermined number of other adits on the southeastern part of the
claim.
Lovely Rogers (Cherokee, Shinier) Mine. Location: Center sec. 11,
T. 3 S., R. 17 E., M.D., in a saddle half a mile south of the Gentry
Gulch road and 1 mile west of the Hasloe mine. Accessible by road via
the Martin Walling or Gold King mine. Ownership : Mrs. Nettie Shinier
Hauck, et al., Yosemite National Park, California, owns one partially
patented claim of 12.57 acres.
The Lovely Rogers mine was discovered by a Cherokee Indian named
Rogers in 1857 (Browne, 1868, p. 32). Rogers operated the mine by
hand methods for several years, recovering gold from high-grade sur-
face ore by crushing the ore in a hand mortar. In 1859 an 8-stamp
steam mill and two arrastras were built, ore milled yielding $35 per
ton. The mill apparently never paid its way and was sold at sheriff's
sale in the early 1860s. During the 1880s and 1890s the mine was
worked intermittently by the Shimer Brothers and ownership has re-
mained in the Shimer family up to the present. There has been no
recent work done on the mine.
According to Laizure (1928, p. 96) there are three more or less
parallel veins on the Lovely Rogers claim. None of the veins exceed 3
feet in width. The principal vein is narrow and sinuous and the strike
varies from N. 56° W. to N. 73° W. It dips about 70° northeast. Wall
rocks are slate and massive quartz-biotite rock that is commonly horn-
felsic. These are metasediments belonging to the Paleozoic Calaveras
group. The metasediments are cut by several narrow, dark granitic
dikes.
Principal workings are a shaft 100 feet deep and three adit levels,
400, 300 and 250 feet long, respectively. There is also a 70-foot crosscut
and an 80-foot winze from one of the adit levels, several shallow shafts
or pits on the northwest third of the claim and numerous open cuts
along the vein over the southeast two-thirds of the claim.
Malone (Bear Creek) Mine. Location : Sec. 5, T. 5 S., R. 19 E., half
a mile east of Bear Creek School and State Highway 140 and 1| miles
south of Midpines. Ownership : Not determined.
The Malone mine was located in 1880 and carries the discoverer's
name. In 1881 the shaft was down 60 feet with George McCaffery super-
intending the operation for Malone (Min. and Sci. Press, vol. 42, no. 18,
p. 276). In 1883 the property was being operated under lease by J.
Mitchell and Company. These operators had a 5-stamp mill working
and were driving a tunnel (Min. and Sci. Press, vol. 46, no. 16, p. 268).
The mine was intermittently active under adverse conditions through
the 1880s constantly hampered by inadequate financing. McCormick
and Hay were the operators in 1889 and Koch and Mitchell in 1890
(Min. and Sci. Press, vol. 61, no. 5, p. 70 and no. 13, p. 202). In 1914
Nos. 1 and 2] mines and mineral deposits, mariposa county 123
W. H. Johnson operated the mine and 5-stamp mill (Min. and Sci.
Press, vol. 108, no. 23, p. 945). By 1915 ownership had passed to
the Golden Wreath Mining: Company (Lowell, 1916, p. 587) but the
mine had to be sold that year to satisfy debts incurred by the company.
Between 1915 and 1919 the property was intermittently active, prin-
cipally by Thomas Gordon and associates. Will Johnson worked the
mine for a short time in 1919 (Castello, 1921, p. 122) under lease from
Gordon, and three men also leased it for a while in 1935 (Laizure, 1935,
p. 37). The property has been idle for many years. It is on patented
agricultural land.
A series of five roughly parallel, narrow quartz veins crosses the Malone
property. The main vein strikes N. 35° W. and dips 35-40° SW. It
varies from a few inches to 3^ feet wide. The other veins are narrower
and less persistent. The veins cut a small, roughly circular intrusion of
granitic rock three-quarters of a mile in diameter which has intruded
schistose and massive greenstone. The eroded upper parts of the veins
apparently yielded considerable placer gold prior to 1880. Vein matter
is ribbon quartz containing thin sheets of altered wall rock, abundant
auriferous pyrite and some free gold (Preston, 1890, p. 300-302). The
principal ore shoot is over 350 feet long and pitched steeply northwest.
It has been stoped to a depth of about 90 feet but the total depth of
the shoot has not been reached. According to Preston (1890, p. 302) the
ore averaged about $14 per ton at a price of $7.50 to $18.00 per ounce.
Workings consist of a 200-foot inclined shaft, which reaches a vertical
depth of 140 feet, 2 airshafts 30 and 75 feet deep, respectively, and a
drift adit and connecting crosscut tunnel 600 feet long.
Malvina Grouv (Potosi, Mahoney, Douglass, D. Cook, Merced).
Location: Sees. 4^ 9, 10, T. 3 S., R. 16 E., and sees. 32, 32, T. 2 S., R. 16
E., M.D., along Maxwell and Black Creeks just west of Coulterville.
Ownership: Walter J. Lautenschlager, 626 So. Catalina St., Los An-
geles 5, California, owns 14 patented claims and several mill sites
aggregating over 300 acres.
The Malvina and adjacent claims were first located in 1852 (Good-
year, 1888, p. 347). According to news items in the Mining and Scien-
tific Press much of the early work was done by the Maxwell Creek Min-
ing Company more popularly known as the French Company. F. L. A.
Pioche was the principal owner in the company. In 1867 most of the
claims on the Malvina vein were sold to Douglass, Chamberlain and
Company of San Francisco, Gilbert Douglass being the principal part-
ner. By the end of that year four shafts had been sunk but the portion of
these shafts was not recorded. A 440-foot adit was also driven which
followed the vein for 330 feet (Logan, 1935, p. 183). By 1876 the
Douglass Company had erected a 20-stamp, steam-driven mill on or near
the Potosi claim. About 1878 the claims on both the Malvina and Mary
Harrison veins were sold to Seth Cook and Company. This company
rapidly acquired properties in the Coulterville district which ulti-
mately aggregated 22,000 acres. In the spring of 1880 the Cook Com-
pany commenced driving a tunnel from Black Creek south for more
than 3,000 feet to get under the supper workings of the Malvina claims.
This was completed in 1881 and was used for many years as a haulage-
way for ore from the Malvina and adjoining claims to the Potosi mill.

Operations by the Seth Cook and Company apparently ceased about
1882 and the properties remained idle until about 1894 when the Cook
Estate was acquired by the Merced Gold Mining Company. This com-
pany was headed by John \Y. Mackay, John P. Jones and Alvinza Hay-
ward. Captain Couch and Captain Ward were their mine superintend-
ents. The Merced Company was unable to keep the grade of ore suffi-
ciently high to pay expenses. The Malvina mine was closed down on
August 1, 1897 and the Mary Harrison later that year. The Malvina
group remained idle until 1910. For a short period that year the D. E.
Lutes Company operated the Mahoney claims. In 1911 H. P. Daulton of
Alameda did some work on some of the claims on both the Malvina and
Mary Harrison veins but was unsuccessful in making any sustained
production (Mining and Sci. Press, vol. 102, no. 18, p. 640, 1911). By
j 920 ownership had passed to A. S. Bigelow and G. M. Hyams of Bos-
ton and some work was done at the mine superintended by C. I. Ment-
zer of Coulterville (Castello, 1921, p. 123). According to Castello the
ore averaged about $4 per ton. In 1933 the Boston California Mining
Company, headed by Charles H. and Eric Segerstrom of Sonora, began
nn watering the Malvina mine to sample 250,000 tons of .2 oz. per ton
ore believed to be present from old mine records (Julihn and Horton.
1940, p. 104). By November 1934 the 1010-foot shaft had been recon-
ditioned and exploration revealed a substantial quantity of $10 ore.
From 1938 to 1942 the company milled 121,093 tons of ore which
yielded 13,197 ounces of gold, 1460 oz. of silver, 4988 lbs. of lead and
24,548 lbs. of copper or an average of $3.82 per ton in gold. The prop-
erties have been idle since 1942.
The Malvina group of claims is on the Malvina vein which is ^en-
erallv recognized as the west branch of the Mother Lode in the Coul-
terville area. The vein is almost continuously traceable from the Ritters-
hoffen claim on the south to the Mahoney claim on the north, a distance
of about 2^ miles. The strike of the vein is N. 45-50° W. and the dip
is 56-75° NE. In the Potosi Tunnel the Malvina vein is only 2 feet
thick for much of the exposed distance (Goodyear, 1888, p. 347). Else-
where it reaches thicknesses up to 20 feet, and the average thickness is
about 10 feet. According to Goodyear (1888, p. 347) the Potosi tunnel
on the Malvina No. 1 claim developed an ore shoot 400 feet long from
which 3,000 tons of ore wTere taken wThich averaged $7 a ton at the old
price of gold. Ore minerals are principally native gold and auriferous
pyrite in a ribbon structure of milky quartz and slate. Quartz-
mariposite-ankerite rock is locally present. Wall rocks are chiefly sandy
slate although Logan (1935, p. 183) mentions a strip of greenstone
occurring on the hanging wall side of the vein and the vein has formed
only a few hundred feet from the contact between slate of the Mari-
posa formation and pyroxene andesite greenstone of the Penon Blanco
member of the Amador group, both formations of Upper Jurassic
age. The Mariposa slate occupies a synclinal trough faulted off on the
northeast by the main branch of the Mother Lode thrust. West of the
Malvina vein and north of the Potosi claim there are conglomeratic-
beds near the base of the Mariposa formation containing quartz and
slate pebbles. These beds were first described by H. W. Fairbanks in
1890. The Mariposa formation is in gradational depositional contact
with the greenstones of the Amador group in this vicinity.
126 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
The principal workings and the ones most recently used (1938-42)
are a 3-eompartment, 1010-foot vertical shaft with levels at 200, 400,
600, and 900 and 1,000 feet on the Malvina claim and a 3,000 foot
haulageway tunnel extending from the Malvina to the Potosi claims.
There are more than 2287 feet of drifts and 1225 feet of crosscuts on
the five levels. There is also an older inclined shaft 875 feet deep
sunk on the Malvina claim, several airshafts and tunnels on the Potosi
claim and numerous other workings on claims north of the Potosi, par-
ticularly on the Mahoney. None of these was readily accessible in
September 1954. Most of the known ore has been stoped above the
600-level on the Malvina and Potosi claims. There was formerly a
shaft at least 350 feet deep on the Potosi claims near the old mill site
which had 9 levels in 1944 (Lowell, 1916, p. 594). The upper part of
the shaft was filled to mill level in September 1954.
The total recorded production of the Malvina group is approxi-
mately $867,800 in gold, silver, lead and copper. Including the early
production of the mine, of which there is no precise record, the claims
must have produced more than $1,000,000. By far the largest propor-
tion of this total was amassed in the periods 1897-1903 and 1938-1942.
The average tenor of ore during these periods was $4 per ton although
nearly half the recorded production was made during a time when
gold only brought $20.67 per ounce. Much of the ore mined in the
1800s would have yielded $7-8 per ton at the present price of gold.
Marble Springs (Compromise and Eubanks) Mine. Location: Sees.
30, 31, T. 2 S., R. 18 E., in the Bull Creek district U miles west of Bull
Creek School and 2 miles south of Bower Cave. Accessible by good
partly surfaced, partly graded dirt road from Coulterville or by graded
dirt road from Briceburg on Highway 140. Ownership : George B.
Glenn, 3134 East 10th St., Oakland 1, California, owns two patented
claims, the Compromise and Eubanks totaling 41.3 acres.
The Marble Springs mine was discovered in either 1850 or 1851
(Browne, 1868, p. 32; Eng. and Mill. Jour. Vol. 101, no. 4, p. 201,
1916). It was equipped with a 5-stamp mill using wooden stamps, one
of the earliest mills built in California. According to Browne (1868,
p. 32) the first owner failed to make the mine pay, and sold it to a
partnership who operated about 8 years at a loss, even though the ore
ran $25 per ton. After a period of idleness of several years duration the
mine was purchased and reopened about 1866 by H. G. Coward. A new
mill was built, the old mill having been removed. Some specimen ore
was taken out by Coward that ran as high as $900 per ton and the mine
was noted for the production of gold-bearing quartz for jewelry
(Browne, 1868, p. 32). By 1869 the mine had again become idle, fire
having destroyed the mine buildings. By 1879, ownership had passed
to A. G. Black. In 1881, the mine was reopened, presumably by an
English company, and a new mill and hoisting works were built. The
shaft, which was 100 feet deep in 1879 was deepened to 400 feet, several
hundred feet of drifts were run. and a substantial quantity of high-
grade ore was taken out using Chinese labor. The amount produced
during the period 1881-84 was not recorded. By 1885, the mine again
had fallen idle because of a high-grading dispute between miners and
Superintendent Lawrence (Min. and Sci. Press, vol. 51, No. 7, page
120, 1885). From about 1894 to 1916 the mine was owned by various

members of the Ililliarcl family, first by M. Hilliard and then by P. J.
and W. W. Hilliard. The Hilliards, or their lessees, took out about
$11,500 in gold and silver from the mine between 1898 and 1901 (U. S.
Bureau of Mines records). The mill and hoist buildings were again
destroyed by fire in 1909. In 1910 the Marble Springs Mining and
Milling Company, F. M. Bernou, manager, secured a bond on the Mar-
ble Springs and North Fork mines but was unsuccessful in putting
them into operation. In 1912, J. A. Flink secured an option to purchase
but no deal was consummated until 1916 when a new stock company.
The Marble Springs Gold Mining Company, was organized with R. C.
Haywood and J. H. Flink as principal stockholders (Eng. and Min.
Jour., vol. 101, no. 4, p. 201, 1916). This company continued to func-
tion under various managements and lessees until about 1943, the
principal production periods being 1918-20, 1930, and 1935-43. In 1950
the Glenn-Steintorf Company took over the mine, completely renovated
it, built a new mill head frame and hoist house, sunk the shaft 80 feet
deeper, ran 250 feet of drifts and several raises. Operations were
temporarily suspended in 1952 and Mr. Glenn since has become the
sole owner.
The Compromise and Eubanks veins are segments of the same vein
which strikes N. 10-15° E. and dips 35-47° E. It varies from 2
to 5 feet thick. Vein matter is milky to bluish quartz, in places carrying
thin seams of wall rock, containing native gold, galena, chalcopyrite,
pyrite and probably a little tetrahedrite and arsenopyrite. Old accounts
in the Mining and Scientific Press and by J. Ross Browne (1868, p. 32)
indicate that the main ore shoot was 400 feet long near the surface,
widening and then narrowing somewhat at depth, and that there were
128 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
several other shoots one of which was over 100 feet long. The main ore
shoot pitched moderately south. The vein is almost continuously stoped
above the 300-level for 600 total feet south of the shaft. (Perrin, Tom,
personal communication, 1954). Wall rocks are chiefly massive, blue-
black hornfelsic quartz-biotite rock with some inter-layered greenstone
and occasional slaty and quartzitic strata. These metasediments are
part of the Paleozoic Calaveras group. The vein system is intersected
and accompanied by a fine-grained greenish granitic dike rock approxi-
mating quartz diorite. Dikes of this rock generally strike the vein from
the hanging wall side (Castello, 1921, p. 123) but are not continuous
the full length of the vein.
During the last period of operation, ore taken largely from the
400-level averaged about $10.70 per ton in gold with considerable lead
and a little silver and copper. Much of the ore mined prior to that date
ran better than $25 per ton at the former price of gold. Between 1936
and 1943, a total of 1767 tons of ore milled ran $24.62 per ton at the
present price of gold. Incomplete records indicate that the total pro-
duction of the mine must be at least $200,000.
The principal working is a 470-foot inclined shaft with four levels and
several thousand feet of drifts. There is also a drift adit a short
distance south of the main shaft which is 130 feet long. The vein
has been stoped discontinuously for an aggregate distance of nearly
3000 feet, between the surface and the 300-level. In September, 1954
the shaft was full of water to within 20 feet of the collar. The modern
mill, which includes two jaw crushers, a ball mill, rake classifiers, four
flotation cells, a. cone concentrator and a small Gibson mill, could
quickly be put into shape for operation.
Mariposa Mine. Location : Sees. 23, 24, T. 5 S., R. 18 E., M.D., in the
southeastern edge of the town of Mariposa. Ownership : Mrs. Frank E.
Galhagher, 211 Twenty-sixth St., Merced, California. Under lease to
George Adams of Mariposa.
The following historical summarv is drawn principally from Bradley
(1954, p. 32), Logan (1935, p. 184), Browne (1868, p. 28) and files of
the Mining and Scientific Press and Engineering and Mining Journal.
Discovery of the Mariposa mine is generally credited to Kit Carson
and two associates in the spring of 1849. As early as July 1849, Palmer-
Cook and Company were crushing ore from this mine in a stamp mill.
Credited by some as being the first stamp mill in California, it is cer-
tainly among the first 2 or 3 built in this state. According to Browne
(1868, p. 28) the mine had produced $200,000 before litigation was set-
tled which gave Fremont undisputed title in 1859. From 1859 to 1864
it was successfully operated by a lessee named Barnett, In 1863, Fre-
mont sold Las Mariposas grant to a New York syndicate which, in 1864,
took over direct operatjon of the Mariposa mine. The 40-stamp mill
of the Greens Gulch mine was moved to the site of the Mariposa mine in
1864 and during that year the gross yield of the mine was $84,948 from
ore that averaged $25 per ton (Browne, 1864, p. 29). The operating
syndicate was dissolved about 1868 but the mine continued in operation
until 1870 at which time the shaft was down 275 feet and the vein was
described as 4 to 5^ feet wide at that depth. Although some rich ore
was found on the lower level in 1870, the average grade of ore evi-

dently fell off from $25 in 1864 to $10 or $11 per ton. The mine had
3rodnced $1,500,000 up to the time of its closing in 1870 (Logan,
1935, p. 184). In 1887 the Mariposa Commercial and Mining Company
was organized by San Francisco financiers Hay ward. Flood, et al., but
lothing was done with the Mariposa mine until 1897 when the company
was reorganized by another San Francisco group headed by Fred Brad-
ey. Work of rehabilitating and re-equipping the mine began in Sep-
tember 1899 and was completed in 1900, with William Dodge as fore-
man and F. T. MacGuire as resident manager. From December 1900
to the end of 1915, when mining was halted by adverse wartime con-
ditions, the mine produced a total of 112,379 tons of ore yielding $693,-
205 — an average of $6.17 per ton at the former price of gold. A new
inclined shaft was sunk to a depth of 1550 feet (measured along the
incline) and several thousand feet of drifts was run. In 1927 the State
Highway Commission produced 35,000 tons of crushed rock of un-
announced value from dumps at the Mariposa mine. Between 1927 and
1932 lessees worked the extension of the Mariposa vein, taking out
about 1500 tons of low-grade ore and several small high-grade pockets.
F. E. Gallagher reactivated and re-equipped the Mariposa mine in
1952 and intermittently produced small tonnages of ore mined during
cleanout and development work. By July 1955, the main shaft had
been unwaterecl and cleaned out to a depth of 800 feet and a new 100-
150-ton-per-day-capacity mill put into operation. The death of Mr.
Gallagher early in 1956 suspended activities at the mine. The Mariposa

mine has been among the five most productive in Mariposa County
known production to date aggregating $2,395,405.
The Mariposa vein east of the main shaft strikes N. 70° W. and dips
60-70° SW. Between the main and old shafts the vein branches with
one branch striking off at N. 50° W. Vein widths vary from 2 to 8
feet wide east of the junction line of the two branches. The branches do
not average much greater than 2 feet wide. Vein matter is milky quartz,
commonly ribboned toward the borders by thin inclusions of wall rock,
with native gold, pyrite and arsenopyrite (Browne, 1868, p. 28),
According to Browne there are high-grade pockets in the branch veins
that nearly always contain arsenopyrite. He reported two pockets from
which $30,000 and $15,000 was obtained. East of the vein intersection
the vein matter uniformly contained gold and ore shoots are ill-defined.
Several theories of vein structure are discussed by Julihn and Horton
(1940, p. 155-157).
Workings of the Mariposa mine include the old, now unusable, shaft
475 feet deep, located 350 feet west of the main shaft, and the three-
compartment main shaft 1550 feet deep (measured along the incline)
sunk in the 1900 's. It has 8 levels with drifts as follows (Laizure, 1928,
p. 99).

Most of the ore has been stoped out above the 800-level and there are
a number of raises and crosscuts as well as a drainage tunnel. A dia-
gram of the workings may be seen in the accompanying figure.
The mine is equipped with a 100-150-ton-per-day mill including jaw-
crusher, bank of five stamps, ball mill, jig, Knudsen bowl, amalgamat-
ing barrel, and rake classifier. Mill heads run from $8 to $15 per ton.
mostly in free gold. Pyrite concentrate runs $60 per ton.
Mary Harrison Group. Location: Sees. 3, 10, 11, T. 3 S., R. 16 E.,
M. D., 1 mile south of Coulterville on Highway 49. Ownership: Walter
J. Lautenschlager, 626 South Catalina St., Los Angeles 5, California,
owns 6 patented claims, the Balance, Choteau. Dahlia, Ely, Sheridan
and Venture, and several mill sites totaling nearly 80 acres.
The history of the Mary Harrison group of mines closely parallels
that of the Malvina group, the two groups being operated for many
years by the same company. Discovered about 1852, the mine was op-
erated by the French Company, also known as the Maxwell Creek
Mining Company, through the early years of its development. F. L. A.
Pioche was the principal owner (Goodyear. 1888, p. 346) in this com-
pany. In 1867 the claims on the Mary Harrison vein were sold to
Douglass, Chamberlain and Company of San Francisco. By August
1878 the old inclined shaft on the Mary Harrison claim was down 450
feet (Min. and Sci. Press, vol. 33. Xo. 14. p. 221; Browne, 1868, p.
34). Later that vear the mine was sold bv the Douglass interests to
INos. 1 and 2] mixes and mineral deposits, mariposa county 131
Seth Cook and Company. About November 1894, the Merced Gold Min-
ing Company took over the Cook Estate mines and for the next 2
years did extensive development work on the Mary Harrison group of
claims. The Merced Company discontinued work on other claims on the
Mary Harrison and Malvina veins in 1897 and from that year to 1904
the Mary Harrison mine was the sole producer for the company. Ac-
cording to the historical marker now at the site of the old boiled house
the Mary Harrison mine produced $1,500,000 from ore averaging $7
to $12 per ton at the old price of $20.67 per ounce. According to Logan
(1935, p. 185) between $330,000 and $400,000 was produced between
1895 and 1903, mill returns in 1897 being $5 per ton. Milling was done
at the Potosi mill throughout most of the history of the mine, ore
being hauled to the mill over narrow-gauge railroad by steam locomo-
tive. D. G. Kidder, later Mariposa County Assessor, was the last super-
intendent. A little development work was done on the Mary Harrison
mine in 1911 by H. P. Daulton of Alameda but there was no recorded
production. Sometime prior to 1920 the Merced Gold Mining Company
was dissolved and although the properties have since passed through
numerous ownerships no further mining has been done. All buildings
were destroyed by fire in August 1926 (Laizure, 1928, p. 100).
The Mary Harrison vein is part of a well-defined system belonging
to the main or east vein of the Mother Lode. It is clearly traceable from
the county line on the north to the Virginia mine on the south, after
which its character is less well-defined. Cross sections of the vein are
well exposed in road cuts along Highway 49. The general strike of the
vein is N. 50° W. with dips from 60-75° NE. It is characterized by a
prominent, massive sheet of milky quartz 4 to 20 feet thick between
irregular, ribboned masses of quartz-mariposite-ankerite-pyrite rock.
Because of decomposition of pyrite with formation of sulfuric acid
groundwater the upper parts of the quartz-ankerite-mariposite-pyrite
rock are commonly converted to porous, earthy masses of yellowish
brown oxides of iron and silica. Some of the high-grade ore was taken
from this sort of vein matter but other similar material proved of very
low grade. Adjacent to the vein, wall rocks, which are chiefly slate,
serpentine and greenstone, have been impregnated with pyrite in large
irregular patches, but such material was evidently too low in gold con-
tent to constitute ore. The entire width of vein matter varies from 50 to
more than 100 feet wide and there are extensive horses of schistose
serpentine caught in the vein matter. Along most of the length of the
Mary Harrison claim the hanging wall side generally consists of black
slate and schist assigned to the Paleozoic Calvareas formation (group)
by Turner and Ransome (1895, maps). The footwall side is serpentine
along much of the length of the vein on the Mary Harrison claim but
sheets of black slate and greenstone are in contact with it at some points
farther north. The greenstone appears to be. derived from pyroxene
andesite of Upper Jurassic age and the footwall slate is probably part
of the Upper Jurassic Mariposa formation. The vein occupies a pro-
found thrust-fault fissure along which there has been displacement
aggregating many thousands of feet.
The most extensive ore shoot was encountered on the footwall side of
the central quartz sheet. It had a strike length of 300 or more feet and
was stoped chiefly between the 400 and 700 foot levels. The vein width
132 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
embraced by the shoot varied from 3 to 10 feet. Ore was not obtained
from the central sheet of massive quartz but some ore was found on the
hanging-wall side of the quartz sheet. Large areas of quartz-ankerite-
mariposite rock are barren of values and the bulk of the vein matter
was too low grade to mill. North of the Mary Harrison group of claims
vein matter reaches a width of 300 feet. Although occasional pockets of
high-grade ore were found that touched off stories of high-grading
activity (various issues of Mining and Scientific Press) most of the ore
was of milling grade and yielded $5 to $12 per ton at the old price of
gold. There is no indication of the probable quantity of ore left in the
lower levels of the mine.
Principal workings are a 1200-foot vertical shaft, the most northerly,
with levels at 100-foot intervals, a second inclined shaft, also with levels
at 100-foot intervals and an airshaft of unknown depth. These shafts
are within 250-300 feet of each other in a nearly straight line, and are
open to depths of several hundred feet. According to Logan (1935, p.
185) there are more than 5000 feet of drifts. None of the shafts are
timbered nor are they accessible without hoisting equipment. There are
numerous other workings of unknown extent on the Dahlia, Venture,
Ely and Choteau and Sheridan claims but these are largely caved and
inaccessible. There has been no recent activity on any of the claims.
Mexican I Mine. Location: NEi sec. 23, S.E. J, sec. 28, T. 4 S., R.
17 E., 1^ mi. south of Bear Valley. Ownership: Not determined; prob-
ably Ellen T. Simpson, et al.
The Mexican mine was discovered sometime during the 1850s and was
worked by Mexicans up to the time Fremont gained undisputed title to'
Las Mariposas grant in 1859. Over $50,000 is supposed to have been
taken from a shallow pit prior to the time ownership passed into Fre-
mont's hands (Julihn and Horton, 1940, p. 130). In 1908 a pocket
containing $62 was taken out and a 150-foot shaft was sunk (Mari-
posa Mining and Commercial Company records). In 1934 the mine
passed into control of Hickman and Dolman but little or no work was
done on the Mexican mine by the company. Between 1934 and 1940
water for the Dolman mill was pumped from the shaft of the Mexican
mine.
Striking N. 35° W. and dipping 70° NE., the Mexican vein follows
the approximate contact between slate of the Upper Jurassic Mariposa
formation and pyroxene andesite greenstone of probable LTpper Juras-
sic age. Greenstone forms the west or footwall side of the vein and slate
the hanging wall side. The vein system is discontinuous and is made up
of a series of subparallel members and intersecting cutter veins. The
upper part of the vein apparently contained pockets of high-grade ore
formed by oxidation and removal of valueless sulfide minerals. There is
little indication that rich ore was found at depth, but the vein was
never thoroughly explored because of the large amount of water to be
dealt with in the workings.
Mockingoird (Talc, Lacy) Mine. Location: Sec. 27, 4 S., 18 E.,
M. D., 1 mile south of Colorado School and 5J airline miles northeast
of Mariposa. Accessible by 4 miles of good dirt road from Summit Inn
on Highway 140. Ownership : David W. and Maxie S. Dukes, 612 Black-
burn, Watsonville, California own 1 patented claim of 20 acres.
Nos. 1 and 2] mixes and mineral deposits, mariposa county 133
The Mockingbird mine, known prior to 1900 under the names Tale
and Lacy, was discovered sometime prior to 1890. It is characteristically
a pocket mine noted for specimens of wiry and arborescent gold ( Pres-
ton, 1890, p. 304). Through the 1890s it was operated principally by
George Lacy of Mariposa (Storms, 1896, p. 219). In the early 1900s the
property passed into the hands of J. A. and C. J. Schroeder of Mari-
posa and remained in the Schroeder family until the 1950s. No work
has been done on the property in recent years. Much of the work on the
mine was done bv the Weston Brothers prior to 1920 (Castello 1921
p. 126).
Gold occurs at the borders of a nearly vertical, chloritic, altered
greenstone dike which strikes N. 40-45° W. More precisely it occurs
where gently dipping quartz stringers cutting the dike contact the
slate wall-rocks (Preston, 1890, p. 304). The altered dike, averaging
approximately 3 feet wide, consists in most places of a talcose, chloritic,
clayey mass including quartz stringers a fraction of an inch to several
inches wide. During the early years of mining the gold was sluiced or
hydraulicked.
According to Castello (1921, p. 126) there is also a northwest-trend-
ing quartz vein containing free-milling ore. He describes a shaft 100
feet deep with drifts and a tunnel several hundred feet long. The prop-
erty was not visited during this investigation.
Mount Buckingham (Vanderbilt, Sunset III, Crown Point) Group.
Location: Sees. 1, 2, 11, 12, T. 5 S., R. 19 E., M.D., near the southeast
end of Mount Buckingham above Snow Creek, 1 mile west of Darrah.
Ownership : Helen M. Ketler et al., 3325 Kempton Ave., Oakland, Cali-
fornia owns one patented mining claim, the Vanderbilt and about 300
additional acres of patented mining and timber land.
The Mount Buckingham group of mines was first located by William
Buckingham in 1850 (Castello, 1921, p. 127). Prior to 1869 an 8-stamp.
water-powered mill was built near the mine (Min. and Sci. Press, vol.
18, no. 6, p. 86, 1869). In April 1871 George Bernhard completed an
80-foot tunnel that exposed a 2-foot vein showing free gold. In 1883 a
crosscut adit was started that had reached a length of 400 feet by 1885
(Min. and Sci. Press, vol. 46, no. 33, p. 221, vol. 50, no. 26, p. 416). Hall
and Starr were the owners in the early 1880s. Ore was described as
running $10 to $15 per ton. By 1889, ownership had passed to a man
named MacDonald who is reported to have recovered $2,000 in one
cleanup, representing 20 days of milling (Min. and Sci. Press, vol. 58,
no. 13, p. 234). In 1893 Judge Condon of Mariposa was listed as super-
intendent but the mine was largely idle that year. In 1894 the mine
was owned by a partnership in which George Beebe was the principal
partner. In 1895, W. S. Chapman, of the Hite mine, purchased an
interest in the Mount Buckingham and the Sunset Mining Company
was organized with George Beebe acting as superintendent. A new 10-
stamp mill was built on Snow Creek half a mile east of the mine (Storms.
1896, p. 224). By 1904 ownership had passed to Mrs. Eliza J. Starr of
San Francisco (Wilkinson, 1904, p. 13). In 1916 a landslide damaged the
adit and buried 200 tons of ore lying on the dump. From about 1912
to 1916 the mine was intermittently operated by the Mt. Buckingham
Gold Mining Company of Mariposa, J. L. Diven of Mariposa, superin-
134 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
tendent during much of this period (Lowell, 1916, p. 589). By 1920
ownership had passed to J. L. Diven and Mrs. C. A. Morgan but by
1928 Mr. Diven was listed as sole owner (Castello, 1921, p. 128; Laiz-
ure, 1928, p. 102). The properties apparently were idle during the
1920s but were operated for a short time in 1930-31, producing a small
tonnage of ore running slightly less than 0.2 oz. of gold per ton. There
has been no recent work done on the mine and there is little record
indicating the total production.
Five more or less parallel quartz veins have a general northwest
strike and dip southwest at angles between 70 and 85 degrees. Vein
widths vary from 2 to 25 feet. One of the veins is accompanied by a
granitic dike in which gold has been deposited. Others associated with
granitic dikes are relatively barren of gold. The veins cut a roof-
pendant of chiastolite-mica schist, most of the surrounding rock being
granitic. Vein matter consists of glassy and milky quartz, ore shoots
carrying abundant pyrite as well as some native gold. Much of the ore
milled in the 1880s returned from $12 to $15 per ton with pyrite con-
centrates running as high as $900 per ton. Most of the ore encountered
in later development work was considerably lower in grade, much of it
running only $3 to $4 per ton. Ore mined in 1930-31, totaling 252 tons,
averaged about 0.2 oz. of gold and 0.2 oz. of silver per ton.
The principal working is a 500-foot crosscut tunnel with a connecting
250-foot raise, 30-foot winze and 2 large stopes. There are several open
pits and minor workings.
Mount Gaines (Bar field, Frenchman, Bearfield) Mine. Location:
Sees. 35, 36, T. 4 S., R. 16 E., M.D., on a tributary to Burns Creek \\
airline miles northeast of Hornitos. Accessible via 5^ miles of the sur-
faced Hornitos-Bear Valley road. Ownership: J. W. Radii, 444 Cali-
fornia St., San Francisco, Calif., owns over 300 acres of patented
mining and agricultural land.
The first mining done in the vicinity of the Mount Gaines properties
was placering of Burns and Eldorado Creeks carried on from 1853 to
1873 (Julihn and Horton, 1940, p. 122). Lode mining began about
1868 on pockets and narrow stringers, vein matter being crushed in
arrastras. In the early 1870s a 400-foot vertical shaft was sunk on the
Frenchman claim about 2000 feet northeast of the present main shaft.
These workings yielded about $100,000 according to Julihn and Horton
(1940, p. 122). These authors state that "beginning in 1880, three suc-
cessive mills were built on the Mount Gaines property, two having been
destroyed by fire and the third by flood." Shallow surface workings
supplied most of the ore crushed in these mills, but $150,000 was re-
covered from ore mined on the Barfield (also called Bearfield) claim.
About 1881 the Mount Gaines mine was purchased, along with a large
group of mines in the vicinity of the Number Nine mine, by the Yose-
mite Mining Company in which M. Hiding, a Pennsylvania oil man
was the chief owner (Mining and Scientific Press, several entries,
1881). Four thousand dollars was reported as the purchase price. This
company operated the mine intermittently or leased it to various groups
until about 1904 when it was sold to the Consolidated Mining and
Processing Company of Los Angeles, W. T. Carter, secretary. Prior to
this sale in 1904 considerable ore had been milled from the Barfield
claim.

The main shaft, started by the Yosemite Company in 1881 was down
300 feet by 1897. At that depth the vein was reported to be 5 feet wide
and the ore to average $25 per ton. The Consolidated Mining and Proc-
essing Company failed to get the mine into production and after a
period of inactivity of nearly 3 years the Mount Gaines Mining Com-
pany was organized in 1906 with A. R. Gaines of Los Angeles as the
principal owner and manager. Under this management, which operated
the property until 1911, the shaft was deepened to 1322 feet and many
thousands of feet of drifts were run. Mine production from 1900 to
1911 totaled nearly $1,000,000 (Julihn and Horton, 1940, p. 122).
Operations by this company ended in indebtedness and litigation in
1911. In April 1914, a group of Denver and Los Angeles men headed
by A. M. Gillespie attempted to reopen the mine but was unsuccessful.
About 1917 another company, the Mount Gaines Gold Mining Com-
pany, was organized with G. W. Crotts and Serona E. Crotts as princi-
pal owners and W. J. McCray as superintendent. Considerable ex-
penditure was made for equipment but indebtedness and litigation
hampered the various managements and no material mining was ac-
complished during the 1920s.
In May 1934 the mine was leased to International Mining and Milling
Company of Los Angeles and soon was put into operation under the
direction of Nelson L. Wagner. This company went bankrupt in 1939
with the Mount Gaines mine its only productive and profitable asset.
From 1939 to 1949 the mine was operated under the control of the Fed-
eral Bankruptcy Courts, Mr. J. P. Hart of Reno, Nevada acting as op-

John L. Dynan. The operating profits from the mine for that 10-year
period were substantial and were used to pay the very high litigation
costs connected with the various bankruptcy claims and procedures. Mine
development was kept at a minimum during that period and it was
largely through lack of development that the mine ceased to be profit-
able. A small production was recorded in 1951-52 in a mill cleanup but
the mine was idle until 1956 when the present owner began exploration
and development works.
Although production records are not complete the gross production
of the Mount Gaines mine is estimated to be at least $3,590,000. From
1932 to 1947 the ore averaged more than half an ounce of gold per
ton in addition to substantial quantities of silver, copper and lead,
giving an average of approximately $19.79 per ton. The Mount Gaines
mine ranges among the 5 most productive mines in Mariposa County.
The Mount Gaines mine is on a northeast-trending vein system that at
the surface is not very well defined. Much of the early work on the
veins was done on pockets and stringers of sulfide-bearing quartz and
the main branch of the vein system was discovered at depth. In the
main vein, which is sinuous, the best ore tends to be concentrated on
the east sides of arcuate irregularities, particularly along the parts of
the vein having the gentlest dip. (Frederick, Francis H., personal com-
munication, 1956). Shoot lengths vary from 40 feet to 450 feet long.
The main vein strikes about N. 35° E. and dips southeast at an average
dip of 20°, but dips vary from 10° to 30°. The vein system has a
known length of about 9000 feet and has been developed for a strike
length of more than 2000 feet and a depth of over 1300 feet, measured
on the incline. It varies from a few inches to more than 15 feet wide
averaging about 5 feet wide. Vein matter is chiefly milky quartz, but
some ore occurs in quartz veinlets in fractured, slaty to chloritic green-

stone along the footwall. Ore shoots contain about 3 percent sulfides.
Ore minerals include native gold, galena, sphalerite, chalcopyrite,
pyrite, arsenopyrite, barite, proustite and argentite, according to
Julihn and Horton (1940, p. 123). Deposition of pyrite preceded that
of galena; sphalerite and gold were deposited later than the pyrite.
No high-grade ore was observed on the dump at the time of the authors'
visit in September 1954. Wall rocks are chiefly massive pyroxene*
andesite greenstone belonging to the Penon Blanco member of the
Upper Jurassic Amador group, but there are some slaty and horfelsic
metasediments in the section. Shearing and hydrothermal alteration
along the vein have caused widespread development of schistose, chlor-
ide, slate-like material, particularly on the footwall side of the vein.
Hornblende granodiorite dikes apparently have penetrated the vein
fissure in many places as there is considerable material of this kind on
the dumps. Julihn and Horton (1940, p. 122) describe a prominent
dike on the hanging wall side of the main vein.
The disposition of the principal workings may be seen in the accom-
panying diagrams. The main inclined shaft is 1322 feet long, measured
on the incline, and has 13 drift levels at 200, 270, 350, 400, 500. GOO,
700, 800, 900, 1000, 1050, 1100 and 1200 feet. There are more than
11,000 feet of drifts and 1200 feet of raises. The principal develop-
ment has been northeast of the main shaft. There is also a tunnel
driven N. 20° E. which was not accessible in September 1954. The
main shaft and workings were watered within 20 feet of the collar
of the shaft. The mill and hoisting equipment were partly dismantled
and rehabilitation of mine and buildings will require considerable
capital outlay.
Mount Ophir. Location: Sec. 12, T. 5 S., R. 18 E., M.D.. 1 mile
northwest of Mount Bullion close to the south side of Highway 49. Own-
ership : Mariposa Commercial and Mining Company, c/o Eileen Mil-
burn, Mariposa, California, owns a large tract of land, a portion of the
old Las Mariposas Grant, which includes the Mount Ophir. Louis,
Mountain View and Greens Gulch mines.
The Mount Ophir mine is one the most accessible and conspicuous of
the Mother Lode mines in Mariposa County. Massive white quartz of
the Mother Lode crowning the summit of Mount Ophir makes a prom-
inent landmark along Highway 49. Close by are the ruins of the
Mount Ophir mint which manufactured octagonal gold slugs from
locally mined gold in 1850-51. Discovered in 1849 or 1850. it was
worked extensively up to the time Fremont gained title to Las Mari-
posas Grant in 1859 and intermittently thereafter until 1914. Three
months of operation in 1860 grossed $43,000 from 1845 tons of ore
for an average of $23.20 per ton (Julihn and Horton. 1940. p. 112).
Browne (1868, p. 29) states that the yield in 1864 was $12,540. From
1864 to 1901 little or no work was done on the mine. The reorganized
Mariposa Commercial and Mining Company, which took over the Las
Mariposas Grant in 1897, reactivated the property in 1901. Between
that year and 1914 a total of 2366 tons of ore was mined which yielded
$29,252.75 or an average of $12.37 per ton at the old price of gold.
Although the mine was examined by George R. Barnett of San Fran-
cisco in 1935, under option to purchase, and although available records
140 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
indicate that the mine was not worked out, there has been no produc-
tion since 1914. The estimated total production of the Mount Ophir
mine is between $250,000 and $300,000 (Julihn and Horton, 1940, p.
112) but the recorded production is $85,703.
At the Mount Ophir workings, the Mother Lode strikes N. 55-60°
W. and dips 55-65° NE. Vein matter crowning' the hill is at least 30
feet wide. According to Lowell (1916, p. 590) the vein averaged 5 feet
wide in the workings. Only stringers are visible in the lower tunnel
which has been driven at the contact of schists of the Paleozoic Cala-
veras group, which forms the hanging wall, and serpentine which
forms the footwall. Both of these units have come in along a fault-
zone cutting the Mariposa slate. Veinlets of quartz penetrate the ser-
pentine walls and locally form stockworks. There is very little mari-
posite-ankerite rock in this segment of the Mother Lode system. Ore
shoots apparently are confined to the footwall and hanging wall sides
of the vein, the central milky quartz being relatively barren of ore
minerals. The larger ore shoots apparently were concentrated on the
footwall side. One pocket of ore was found in a vein on the footwall
side of the main vein in 1913 that yielded $711.65 (Laizure, 1928,
p. 98). Ore mined in the early days apparently averaged a little better
than $23 per ton whereas ore mined in the 1900 's averaged a little
over $12 per ton, both these figures at the old price of gold. According
to a report made in 1922 by Frank Eichelberger (Julihn and Horton,
1940, p. 112) the workings at that time contained 4000 to 5000 tons of
developed ore averaging 4 feet wide that would mill $9 to $11 per ton.
He further stated that nearly all the development work had been
carried on on the footwall side of the vein with little or no exploration
of the hanging wall side.
Principal workings are two adits, one about 115 feet above the other,
both driven on the vein from the north side of the hill. The lower tun-
nel, 700 feet long, reaches a vertical depth of 250 feet below the top of
Mount Ophir. This tunnel was accessible in August 1955 although in
need of cleaning out. The upper adit is 320 feet long but is partly
caved. A third adit, mentioned by Lowell (1916, p. 591) could not be
located and presumably is caved. At the summit of Mount Ophir are
two open stopes or air shafts each at least 100 feet deep which could
easily be cleaned out as accessways. According to Lowell, there were
1500 feet of drifts, 360 feet of raises. 80 feet of crosscuts and one
large stope in 1916.
Mountain King (Omparisa, Calender and Calendonia) Mine. Loca-
tion: Sec. 31, T. 3 S., R. 18 E. and sec. 6, T. 4 S., R. 18 E., M.D., on the
north side of the Merced River Canyon 1 mile east of Quartz Mountain
and 6 airline miles east of Bagby. Accessible by 5| miles of good dirt
road from Briceburg on Highway 140. Ownership : 13 of the claims
are owned by J. W. Radii, 444 California St., San Francisco 4, Cali-
fornia and 5 claims are owned by Ralph E. Dailey, 1165 Twenty-second
St., Merced, California.
Very little concerning the early history of the Mountain King mine
has been recorded. It was being developed in 1899 by Egenhoff and
Merritt who were running a tunnel designed to tap the vein 1500 feet
from the surface. In 1904 the properties were bonded to the Omparisa
Xos. 1 and 2] mixes and mineral deposits, mariposa county 141
Mining Company headed by H. C. Austin for $40,000. (Mill, and Sci.
Press, vol. 88, no. 12, p. 122, 1904). H. A. Kunz was one of the first
superintendents under this company which started a crosscut tunnel
to intersect the 5 parallel veins cropping out higher on the hill. A
5-stamp mill was completed in March 1905 and this was increased to
10 stamps in October the same year. Several high-grade ore-shoots were
found in 1909 and the mill was increased to 20 and then to 40 stamps.
William S. Thompson was superintendent 1910-1911. After a short
period of inactivity the Mountain King Mining Company was organized
in 1914 and took over the holdings of the older company. Alexander
Hamilton was superintendent in 1915 and B. C. Austin in 1917. Opera-
tions by this company ceased in 1922 because operating costs rose above
mill returns. The mine has been idle ever since except for a little leasing
activity between 1922 and 1925.
From 1909 to 1925 the mine produced 162,800 tons of ore vielding
39,833.51 oz. of gold and 18,042 oz. of silver for a total of $825,425.65
and an average value per ton of $4.51 (at the former price of gold).
Estimated total production of the mine is nearly $1,000,000.
Five persistent veins as well as a number of smaller ones cross the
Mountain King properties at the surface. Four of the 5 main veins
have been identified in underground workings and a fifth was dis-
covered during development work that does not reach the surface. The
principal veins are the Mountain King, Flat 01, Back or No. 3, McFad-
den and Big Flat Footwall. Production thus far has come only from
the Mountain King and Flat 01 veins. The McFadden, Mountain King
and No. 3 veins are roughly parallel, strike N. 20-25° W. and dip
65-80° N.E. The Big Flat Footwall vein strikes southwest and dips
northwest. The Flat 01 vein appears to diverge from the steeper Moun-
tain King vein about 800 feet from the surface at about the 200-level.
The best grade of ore taken from the Mountain King mine came from
between the 200- and 300- levels of the Flat 01 vein during the period
1910-12.
Three ore shoots, numbered 1 to 3, east to west have been found and
worked in the Mountain King vein. The No. 1 oreshoot is known to
extend from the surface, at the collar of the Egenhoff shaft to a known
inclined depth of 1000 feet and was still well defined at that depth
when abandoned to work the No. 2 shaft. The No. 2 shoot has been ex-
plored between the 850- and 2000-levels where it is known to merge with
the No. 1 shoot near the 2000-level. The No. 2 shoot is 200 feet long,
averages 46 inches thick on the 2000-level and averages $9 per ton at the
present price of gold. The third and most westerly ore shoot dies out
above the 850-foot level but is still well defined near the bottom of the
workings on the 2000-level.
Mountain View I Mine. Location : Sec. 11, T. 5 S., R. 17 E., 2 airline
miles northwest of Mt. Bullion. Adjoins the Louis mine. Accessible by
unimproved dirt road from Greens Gulch via the Louis mine. Owner-
ship : the mine is part of a tract of land containing several hundred
acres, part of Las Mariposas Grant, still held by Mariposa Commercial
and Mining Company, c/o Eileen Milburn, Mariposa, California.
The Mountain View mine was discovered prior to 1859 and its history
has been similar to many other Las Mariposas Grant mines. It appar-
ently was characteristically a pocket mine or at least had small ore
142 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
shoots, and most of the recorded production has been from ore of
fairly high grade. One of the principal periods of production was 1900-
1915 when 376.16 tons of ore mined yielded $17,792 or an average of
$47.52 per ton at the old price of gold. Xo other production records are
available. No mining has been done since 1915.
Both the Mountain View and Louis properties are crossed by the
same vein, which is generally considered to be part of the Mother Lode
system. This vein is roughly parallel and en echelon to the vein passing
through the Mount Ophir mine, the two veins being about 3200 feet
apart. Crossing the Mountain View claim the main vein strikes N. 48°
W. veering to about N. 65° W. crossing the Louis property. The dip
is 60-65° northeast and average width is about 2\ feet. Wall rocks are
black slate of the Upper Jurassic Mariposa formation. Strike of the
slaty cleavage is roughly parallel to the strike of the vein. Vein matter
is milky quartz with pyrite and native gold. Inclusions of thin sheets
of slate give a ribbon-like structure to some parts of the vein.
"Workings consist of 2 adits driven on the vein totaling about 500
feet, 400 feet of crosscuts, 160 feet of raises and a stope 50 feet long
and 100 feet high (Lowell, 1916, p. 591). Milling was done at the
Princeton mill throughout the last period of operation of the Mountain
View mine.
Nellie Kaho. Location: Sec. 4, T. 5 S., R. 17 E., sec. 33, T. 4 S.,
R. 17 E., M.D., 3 miles south of Bear Valley and just west of Cow and
Calf Road. Ownership : Harold Hansen, Mariposa, California, owns a
property consisting of about 20 acres. Under lease (1956) to Harmon
and Gault.
Prior to the late 1930s the Nellie Kaho mine was one of many old
prospects which had never been well explored. Taken over by a group
of leasers including the present owner, in June 1937, about $1400 was
recovered from surface workings (Julihn and Horton, 1940, p. 126).
By 1938 a 100-foot shaft had been sunk which connected with a 50-foot
south drift and a 50-foot east crosscut on the 100-level. The advent of
World War II ended this period of operation. Clyde Diffenbaugh of
Bear Valley did some work on the mine in 1951-52 and the present
operators have worked the property intermittently since 1954.
The quartz vein, one of the Mother Lode system, is about 18 inches
wide and crops out for a distance of 100 feet at the surface. It strikes
northwest and dips about 80° SW. Wall rocks are slate and greenstone.
Ore runs from \ to | percent sulfides, 30 percent of the precious metal
value coming from the sulfide concentrate. This averages 6 to 7 oz. of
gold per ton. The grade of ore mined in the late 1930s ranged between
$10 and $20 per ton with occasional pockets of higher-grade ore.
Workings consist of 2 shafts about 50 feet apart. The main shaft, the
more southerly, is 200 feet deep and is inclined about 85° W. There is
a 50-foot level, a 125-foot level and a 200-level. Recent work has been
on the 200 level. The operators plan to ultimately deepen the north
shaft, now about 50 feet deep, and connect the 2 workings. In 1938 the
workings made 8000 gallons of water per day.
Number Five (Monte Carlo) Mine. Location: Sees. 2, 11, T. 5 S.,
R. 16 E., M.D., 5 miles northeast of Hornitos and 1 mile northeast of
the Number Nine mine. Accessible from the paved Hornitos-Bear Valley
Nos. 1 and 2] mines and mineral deposits, mariposa county 143
road by Xi miles of good dirt road via either the Number Nine or
Mount Gaines mines. Ownership : not determined.
The Number Five mine is an old property consisting of the Number 5
and Jack Quartz claims and the fractional Standby and No. 5 Extension
claims. A small production was recorded in 1899y but the operators'
names were not recorded. The principal period of activity was
1909-1914, operators being the Number Five Mining Company, J. J.
Le Tourneau of Duluth, Minnesota, president and E. S. O'Brien of
Merced, secretary. Various superintendents under the management were
Hugh Branson (1909), Martin Sutherland (1910) and Carl J. Smith
(1911). A 260-foot inclined shaft was sunk with a 300-foot drift on the
100-level and a 56-foot crosscut on the 200-level (Min. and Sci.
Press, vol. 99, no. 2, p. 41, 1909). In 1914 the property was operated
for a short time under bond by the Nevada Mineral Extraction Com-
pany in which S. W. Parker of Berkeley was the principal owner and
C. H. Gage was superintendent. A 50-ton Lane mill was installed (Eng.
and Min. Jour., vol. 98, no. 20, p. 894, 1914). The mine was operated
under lease for a time in 1921-22 and a small production was recorded.
No material amount of mining has been done since 1922 and the land
has reverted to agricultural status.
There are at least three veins on the Number 5 property, the Number
5, Number 2 and south extension of the Prescott. The Number 5 vein, the
most prominent and the most southerly of the group, trends N. 75-80°
E. and dips about 65° north. It ranges from 5 to 30 feet wide and con-
sists principally of milky quartz with abundant pyrite. Surface show-
ings of gossan are common. The Number 2 vein, apparently the one
crossing the Jack Quartz claim, strikes N. 80-85° E. and dips steeply
north. It is much narrower and less well defined at the surface than
the Number 5. The southern extension of the Prescott vein apparently
has been the most extensively worked. It strikes N. 20-30° E. on the
Number 5 property and swings more nearly to the north on the Prescott
claim. Ranging between 1 and 4 feet wide, it dips toward the east at
angles varying from 20 to 30 degrees and blankets much of the hillside
area. Judging from the numerous surficial workings there must have
been numerous parallel blanket stringers in addition to the main Pres-
cott vein. All of the soil mantle in the vicinity of the veins has been
placered. The veins cut a variety of wall rocks, chiefly slate, spotted
slate, schistose greenstone, hornblende schist and hornfelsic slate prob-
ably belonging to the Upper Jurassic Amador group (Taliaferro, 1943,
p. 282). These are cut in places by irregular intrusions of porphyritic
granitic rocks, chiefly granodiorite porphyry.
The main working on the Prescott vein is a long northwest-trending
crosscut adit with extensive connecting drifts and stopes. Laizure
(1928, p. 104) mentions a main shaft 260 feet deep and a second shaft
200 feet deep but does not state the location of these workings. There
are numerous workings on the Prescott vein which could be either shafts
or stope openings. All of the workings are in need of cleaning out and
those on the Prescott vein are flooded below the main adit level.
Number Nine (Bill Jones and McCall, Yosemite, Ginaca) Mine. Lo-
cation: Sec. 10, T. 5 S., R. 16 E., M.D., 2 airline miles northeast of
Hornitos. Accessible via 1-]- miles of improved dirt road from the paved

Hornitos-Bear Valley road. Ownership : W. R. Plunkett and Ulysses M.
Peyrellade, 1278 Twenty-sixth Ave., Oakland, California, own three
patented claims totaling' about 41 acres.
The Number Nine mine was probably discovered in the 1850s and
mined in a small way from surface pits and shallow underground work-
ings. The first owners of record were Major Hardwick and son who
reopened the mine 1873 and erected a mill. Prior to erection of the mill
in 1873-74 ore wras crushed at the Mt. Gaines mill where one run of
2,000 tons yielded $7,375 per ton (Mill, and Sci. Press, vol. 29, no. 4,
p. 53, 1874). In 1880 the mine was sold along with several others to
Marcus and J. W. Hulings of Oil City, Pennsylvania, for $77,000
(Min. and Sci. Press, vol. 41, no. 24, p/372, 1880). At that time the
ore in the mine was sampled and was supposed to average $9 per ton.
A 30-stamp mill was erected which crushed 40-45 tons of ore in 24
hours. Only $l-$2 of the total gold proved to be free-milling and the
first year of operation proved a failure. In 1881 a new milling pro-
cedure, which recovered sulfide concentrates, was introduced and sev-
eral years of profitable operation ensued in which recovery varied from
$6 to $9 per ton and profits from $2-$4 per ton. J. Frank Thorn was
superintendent during this period. A $15,000 chlorination plant was
erected in 1883 but this evidently was not successful. The mine closed
down soon afterward and nothing further was done until 1896 when it
was held for a short time by W. S. Chapman and Associates of San
Francisco. Ownership had passed to Moses L. Rodgers after the Hulings
left. The Chapman management failed to get the mine into production
and it lay idle until 1903 when some cleanout, exploration and develop-
ment work was done by Harmon and Stevens under the direction of
W. F. Stevens. About 1909 the Number Nine Gold Mining Company
was organized, initially with New York capital but later reorganized by
San Franciscans. Richard O 'Brien superintended mine operations from
1909 to about 1911. During this time the old inclined shaft was
re-timbered to the 250 level and then abandoned. In 1910 a new ver-
tical shaft, the Keys was started which ultimately reached a depth of
140 feet (Laizure, 1928, p. 104). Between 1911 and 1919 there was a
little intermittent activity at the property but no sustained mining
(James Peck managed the mine for the Rodgers estate). About 1919
the Number Nine Gold Mining Company was reorganized with L. A.
Ginaca of San Francisco as president. This company moved in new
equipment, unwatered the mine and wras preparing to re-open when
litigation cancelled further work until 1924. From 1924 to 1930 activity
was confined largely to rehabilitation and development work and only
a few ore shipments were made. B. S. Mc Arthur was superintendent
in 1928. Between 1930 and 1936 there was a moderate production of
low-grade ore. There has been no activity since 1936 and all equipment
has been removed.
According to Laizure (1928, p. 104) twelve veins have been discov-
ered on the Number Nine property. The main system strikes north to
N. 20° W. and dips 25-30° E. It is crossed by a secondary, nearly ver-
tical system of east-trending veins. The most prominent vein crops out
on the east side of a low ridge northwest of the Key shaft, blanketing
the hillside for perhaps an acre. Most of the early work apparently was
done on this vein as a great many shallow workings have been driven
Nos. 1 and 2] mines and mineral deposits, mariposa county 145
into it. Vein matter consists chiefly of massive to vuggy milky quartz
3 to 15 feet thick, with very erratically distributed masses of auriferous
pyrite. Wall rocks consist of quartz-biotite schist, gneiss and hornfels
with some small intrusions of altered granodiorite. Although not well
exposed, some of the ore appears to have developed in altered dike
material on the footwall side of the vein. The width of the main vein in
the vicinity of the Number 5 shaft varies from 38 to 44 inches. The
vein exposed in the drift adit 150 feet from the end was 18 inches wide.
Six shafts and a 350-foot drift adit were identified on the Number
Nine property. Four of these shafts are approximately on a line bear-
ing N. 20° W. The most northwesterly of this group is the No. 9 at
least 125 feet deep but long unused. The most southeasterly is the No.
5 shaft 387 feet deep measured on the incline. The shaft serves 3
levels of which the 300-level is most extensive. The No. 9 and No. 5
shafts are about 880 feet apart. Two 30-foot deep shafts are about
evenly spaced in this interval. All these shafts are inclined from 20°
to 28° northeast. The Key vertical shaft is 150 feet deep with the lowest
working level at 125 feet. This shaft is located about 500 feet northeast
of the Number 5 shaft. The Key Extension shaft, also vertical is lo-
cated close to the Mount Gaines mine road about 1000 feet north and
slightly east of the Key shaft. All of the workings have been inactive
for a long time and are in need of rehabilitation.
Nutmeg Mine. Location: Sec. 30, T. 4 S., R. 18 E., M.D., on the
west side of Whitlock Creek 1 mile north of the Permit mine and 4
airline miles northeast of Mount Bullion.
Ownership : Sam Le Barry, c/o Permit Mining Company, Midpines,
California owns one unpatented claim.
The Nutmeg mine is on a north extension of the vein system that
passes through the Milburn, Permit and Geary mines. Little has been
recorded of the early history of the mine but it was discovered prior
to 1900. A moderate production is recorded from 1938 to 1951, a total
of 5239 tons of ore having yielded 1204 oz. of gold, and a little lead
and copper, and 331 oz. of silver. The average yield per ton has been
between $8 and $8.50 although some pockets of ore run as high as 3 oz.
per ton. The mine is still worked intermittently by the Permit Mining
Company under the direction of H. H. Odgers.
The main vein is about 3i feet wide, strikes N. 20-25° W. and dips
steeply east. Wall rocks are massive and sheared pyroxene andesite
greenstone. Four ore shoots have been developed which average 25 feet
long (Julihn and Horton, 1940, p. 152). The principal working is a
106-foot vertical shaft with more than 160 feet of drifts on the 50-foot
level and 300 feet on the 100-level.

The Oakes and Reese mine, discovered in 1863, was one of the famous
early producers in Mariposa County. It has produced between $500,000
and $600,000 (Julihn and Horton, 1940, p. 117), most of this total
coming from the period 1863-1870. The operator in 1865 was J. W.
Adams and Company and in 1870 Robinson and Company. According
to Castello (1921, p. 131) the mine was closed down in 1870 because
of a lawsuit over water rights and because one of the ore-shoots was
mined out. The property was operated under lease in 1870-1871 by
Dan Jones (Min. and Sci. Press, several entries). Much of the ore
mined in the 1860s ran much higher. Early milling was done in ar-
rastras. A 10-stamp mill was built in 1866 which had been increased
to 28 stamps by 1868 (Raymond, 1870, p. 24). The vein had been opened
to a depth of 200 feet by 1868 (Min. and Sci. Press, vol. 16, no. 9,
p. 134).
Except for intermittent small mining by lessees and occasional de-
velopment work the mine remained closed until June, 1937. Some work
was done in the late 1920s by the Oakes and Reese Mining Company,
a New York firm (Laizure, 1928, p. 131). During 1938 a small tonnage
of low grade ore was milled by W. A. Hayes of San Francisco, Thomas
Henry of Hornitos acting as superintendent. No high-grade pockets
were found and the mine shut down in 1939, since when the property
has been idle. The shaft was caved, and all equipment removed in
July, 1954.
The Oakes and Reese mine is located on a well-developed vein of
bluish quartz, called the Blue Lead, that strikes N. 35-40° W. and dips
70-80° northeast. The Blue Lead is intersected, approximately at right
angles, by a series of nearly vertical cutter veins or laterals which enter
the main vein from the east or hanging wall side, and which in general
carry more high-grade ore than the main vein. The two principal lat-
erals, the Potts and Floyd, are approximately 400 feet apart. The main
vein averages 4-5 feet wide and the laterals between 1 foot and 2 feet
wide. A third lateral vein crosses the Blue Lead about 300 feet south
of the Floyd lateral, and there is a fourth still farther south. The Blue
Lead has developed on or close to the contact between the Hunter
Valley chert beds and massive greenstones, both of Upper Jurassic age.
The chert series contains thin-bedded tuffaceous shales and siltstones
as well as chert. The principal ore body was a pipe-like shoot of high-
grade developed at the junction of the Blue Lead with the Potts lateral.
The high-grade ore graded into lower-grade material long the footwall
side of the Blue Lead. According to Julihn and Horton (1940, p. 117)
the ore from the shoot averaged about 2.5 oz. of gold per ton and the
best of it 5 oz. or more.
The main shaft was sunk to an inclined depth of 450 feet at the
junction of the Blue Lead with the Potts lateral. From the shaft levels
were run at depths of 130, 200, 300 and 450 feet, the total amount of
drifting being only about 800 feet (Julihn and Horton, 1940, p. 117).
The Blue Lead vein has been stoped for a strike length of 60 feet, north
of the shaft, and to a depth of 200 feet. The Potts lateral has been
stoped for a length of 282 feet from the shaft on the 130-level and 147
feet on the 300-level (Julihn and Horton, 1940, p. 117).
There are two other shafts 160 and 70 feet deep, respectively, both
sunk at the junction points of laterals and the Blue Lead. Drifting

from these shafts is much less extensive than from the main shaft. The
last work done on the mine in 1938 was the extension of the 200 level
from the main shaft south toward the Floyd lateral.
Oro Rico (Tenon Blanco) Mine. Location : Sees. 19, 20, 29, T. 2 S.,
R. 16 E., M.D., just south of the Tuolumne County line on Highway
49. Ownership : Oro Rico Mines Company, c/o A. D. Vencile, Room 14,
1584 West Washington Blvd., Los Angeles, California, owns the pat-
ented Old Judge, South Judge, Little Judge, Peiion Blanco and North
Penon Blanco lode claims and the unpatented Star and Stevenson
claims totaling more than 100 acres.
The prominent white quartz ridges cropping out on the Peiion Blanco
(White Cliff) are among the best known landmarks along Highway 49.
Oro Rico properties cover more than 2 miles of the Mother Lode be-
tween the county line and Coulterville. Because of its prominence, the
vein was one of the earliest to be worked in Mariposa County. The
Penon Blanco claim, over 5800 feet long, is the longest on record. As
early as 1868 there were two shafts and several tunnels (Browne, 1868,
p. 35) and several ore shoots 2 to 4 feet thick had been discovered. At
that time the ore averaged $10-12 per ton. The first application for patent
was made by the Oro Rico (Peiion Blanco) mine under the act of 1866,
according to Browne. By 1896 there were well over 1400 feet of work-
ings on the property, then owned by A. H. Ward of Alameda (Storms,
1896, pp. 221-222). Ward built a 20-stamp mill and worked various
parts of the property until about 1910 when it was bonded to J. C.
Wilson and associates of San Francisco (Eng. and Min. Jour., vol. 89,
no. 16, p. 839), who did some work on the mine between 1910 and 1912.
The property was tied up for much of the time between 1912 and 1928
because of litigation, and little or no mining was done. During this
period ownership passed to A. E. Tower of San Francisco. In 1934, J. C.
Kempvanee and associates unwatered the mine and did some explora-
tion and development work but little or no work has been done since
that time. The total production, although incompletely recorded, is
small.
The Mother Lode, as it crosses the Oro Rico property, consists of a
single massive vein striking N. 30° W., dipping 52° northeast, and
reaching a thickness of over 250 feet. It is intersected in several places
by small lateral veins. Great thicknesses of vein matter consist of
quartz-ankerite-mariposite rock although the included quartz lenses that
cap the ridges are by far the most conspicuous parts of the vein. Over
much of the vein length the ankeritic portions have been altered by
acid groundwater to spongy masses of iron oxide and silica boxwork.
Ore shoots contain pyrite, chalcopyrite and native gold (Storms, 1896,
p. 221). Toward the southern end of the mine property the Mother
Lode lies close to the contact between slate of the Upper Jurassic Mari-
posa formation and serpentine, also of Upper Jurassic age. Farther
north it is wholly within a large serpentine mass.
In comparison with the size of the vein the ore shoots in this seg-
ment of the Mother Lode proved small and of relatively low grade. The
two shoots mentioned by Browne (1868, p. 35) on the Penon Blanco
claim were 2 and 4 feet thick and averaged $10-12 per ton near the
surface. Inasmuch as these were considerably enriched through re-
148 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
moval of worthless material during* alteration in the oxidized zone, it is
probable that the grade of ore lessened with depth.
In 1868, workings consisted of a 175-foot crosscut adit driven from
the west or footwall side, a 285-foot crosscut adit driven from the east
or hanging* wall side and two shallow shafts 2000 feet apart (Browne,
1868, p. 35). All of these apparently were on the Peilon Blanco claim.
By 1896, there were 2 adits 25 and 100 feet long, respectively, and sev-
eral open cuts on the Old Judge claim ; a 200-foot adit on the North
Penon Blanco claim; and more than 1000 feet of tunnels, drifts and
shafts on the Penon Blanco claim (Storms, 1896, p. 221). According to
Logan (1935, p. 186), the Oro Rico Mines Company drove a 600-foot
crosscut which reached the vein at a depth of 320 feet and more than
1000 feet of drifts were run from this adit. From the floor of the north-
west drift a winze was sunk to a depth of 450 feet and 4 levels of un-
known length were driven. In August 1955, five workings were still
recognizable on the Penon Blanco claim, two adits and a shaft toward
the south end of the claim on the east side of the ridge and one adit and
shaft toward the north end on the west side of the ridge. None of these
workings would be accessible without some cleaning out and none were
entered.
Ortega Mine. Location: Sec. 19, T. 5 S., R. 17 E., sec. 24, T. 5 S.,
R. 18 E., M.D., on Highway 140 midway between Nigger Hill and
Guadeloupe Mountain. Adjoins the Sorrel (Sarle) mine on the north.
Ownership : Frank A. Cassaccia, Mariposa, California owns a tract of
about 125 acres which includes the Ortega mine. Formerly part of Las
Mariposas Grant.
Gold was discovered at the Ortega mine in the early 1850s by a
Spanish Californian named Ortega. He worked the vein extensively
until Fremont gained title to Las Mariposas Grant in 1859." Ten or more
shafts were sunk on the vein over a distance of 1485 feet (Julihn and
Horton, 1940, p. 131), all but two of these being north of Highway 140.
The deepest of the shafts, cleaned out and reconditioned in 1936-37 was
found to be 167 feet deep measured along the incline. Milling was done
mainly in arrastras but some ore was milled in a 2-stamp mill by a
millman named Turner. After Fremont dispossessed Ortega's group in
1859, no further work was done until 1900 when some ore found lying
on the dumps was milled at the Princeton mill and yielded between $14
and $27 per ton (Julihn and Horton, 1940, p. 131). In 1934, a partner-
ship of Price, Willmer, Givens and Givens leased the mine from the
Mariposa Commercial and Mining Company. This group cleaned out
the No. 3 shaft to a depth of 180 feet and ran a drift 125 feet south.
Good ore was found below the old Mexican workings 10 tons of which
yielded $91.60 per ton. However, the quantity of ore developed proved
small and the partnership was forced to withdraw because of insuffi-
cient funds to properly develop the mine. In 1936 John Q. Finfrock
leased the property and operated it until 1940. He cleaned out and
rehabilitated the No. 4 shaft, mined considerable new ore and processed
some old broken ore found on the property. In 1940 the property was
again taken over by Mariposa Commercial and Mining Company and
put in charge of D. Mullins. In 1941 the Ortega mine was one of a group
optioned to J. K. Wadley of Texarkana, Arkansas and placed under the
management of Charles Greenameyer. World War II prevented contin-
Nos. 1 and 2] mines and mineral deposits, mariposa county 149
uation of this enterprise and no further work had been done at the
Ortega mine up to September 1955.
Two veins have been found on the Ortega property. The main vein
averages about 3 feet wide, strikes about N. 20° W. and dips 50-60° W.
It is a continuation of the vein which crosses the Sorrel mine south of
Highway 140. Vein matter is coarse milky quartz containing sphalerite,
pyrite, chalcopyrite, galena and arsenopyrite as well as native gold. At
various places along its length the vein fissure has been intruded by
pegmatite, aplite and dark granitic dikes. The enclosing rock is coarse-
grained biotite granodiorite. A second vein was discovered in the late
1930s about 500 feet east of the No. 4 shaft which strikes N. 30° W.
(Julihn and Horton, 1940, p. 132). This vein has not been well explored
nor has the possible point of junction of the 2 veins been discovered.
A line of caved shafts and stopes extending northwest from Highway
140 marks the position of the old workings. None of these were access-
ible in July 1954 and the various shafts could not be identified. The
shafts were evidently numbered from north to south, no. 2 and no. 3
shafts lying 170 feet apart. The No. 4 shaft, worked by Finfrock in the
late 1930s, was 167 feet deep and had 3 levels at 100, 147 and 167
feet, respectively. According to Julihn and Horton all of the ore above
the 100-level south of the shaft has been stoped. Ore was found in
place on the 147-level from within 60 peet of the shaft to 347 feet south
of the shaft and ore has been found continuously from 30 feet north of
the No. 3 shaft to the No. 4 shaft. The length of one ore shoot must
be at least 527 feet with a width varying from 2\ to 4 feet. Dis-
position of other workings indicates that the vein must have been almost
continuously mineralized for over 1000 feet. The workings in the vicin-
ity of the No. 4 shaft draw 24,000 gallons of water a day (Julihn and
Horton, p. 132, 1940).
The early production of the Ortega mine was not recorded. Julihn
and Horton state that "a total of $19,796 was recovered by Finfrock
from ore taken from the levels once operated by Ortega and from re-
mains of their surface dumps. Of this total, $10,154 was derived from
691 tons of newly mined ore, an average recovery of $14.69 per ton,
and 346 tons of old gob yielded an estimated $5 per ton. In milling,
9700 pounds of concentrates were recovered which assayed $171.54
per ton."
Our Chance (Clark Mines, Albert Austin group) Mine. Location:
Sec. 29, T. 4 S., R. 18 E., on the Sherlock Creek road, 4 airline miles
northeast of Mt. Bullion. Adjoins the Diltz mine on the west. Owner-
ship : Not determined.
The following discussion is drawn chiefly from Julihn and Horton
(1940, pp. 147-148), the last authors to visit the mine while it was op-
erating. The Our Chance mine apparently was first worked by Albert
Austin who is supposed to have recovered more than 2000 oz. of gold
from pockets near the exposed surface of the vein. Austin used a hand
mortar and an arrastra. A pocket taken out by Arthur Clark, the last
operator, yielded about $17,000. Clark operated the mine from 1932
to about 1946, mining and milling a total of 2563 tons of ore yielding
1357.77 oz. of gold and 223 oz. of silver (U. S. Bureau of Mines records)
or an average of about $18.60 at current metal prices. The mine is
noted for its specimens of crystallized and arborescent gold.
150 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
The Our Chance vein strikes northwest and dips about 27° northeast,
the width averaging 14 inches but varying between 4 inches and 4 feet.
Above the vein is a dike of dark granitic rock 4 to 6 feet thick. Wall
rocks enclosing- the vein and dike are pyroxene andesite greenstones of
unknown age. Vein matter is banded quartz with pyrite, chalcopyrite,
arsenopyrite, galena and native gold, in places associated with calcite
and manganese oxides.
The principal working in 1938 was an 800-foot adit driven north-
east to the vein with 2500 feet of connecting drifts, winzes, etc. At the
end of the adit is a 500-foot southeast drift which has a 200-foot winze
sunk 200 feet from the end of the adit. At a depth of 100 feet a level
has been run from the winze 100 feet to the southeast and 70 feet to
the northwest. Above the drift from the main adit ore has been stoped
to a height of 50 or 60 feet between the adit and winze for a length
of 175 feet. Between the winze and the end of the drift there is a 300-
foot stope about 100 feet high. Very little timbering is required. The
mine was idle in October 1955 and there was no equipment on the
property.
Permit (Boulder, Kockel, Bulldog, Bullpup) Mine. Location: Sec.
23, 31, T. 4 S., R. 18 E., M.D., on Whitlock Creek 3 airline miles north-
east of Mt. Bullion. Accessible via the Whitlock-Sherlock Creek graded
dirt road. Six miles north of Mariposa. Ownership : Permit Mining
Company, c/o H. H. Odgers, Midpines, California, owns 5 unpatented
claims, the Aladdin, Aladdin No. 1, Aladdin No. 2, Permit and Permit
Extension.
According to Castello (1921, p. 109) the old Bulldog and Bullpup
claims were located in 1894 but an entry in the Mining and Scientific
Press (vol. 60, no. 14, p. 232, 1890) indicates that the Bulldog mine
operated that year under N. J. Farrens, producing a few tons of low
grade ore. In 1904 (Wilkinson, 1904, p. 10) the owner of the Bulldog
was listed as Czerney and Company of Merced. In 1916 the Bulldog
claim was operated by Theodore E. Kockel of Lyons Gulch and the
Bullpup by Jack Czerney of Merced. At that time there was a shallow
shaft on the Bulldog claim and an inclined shaft 165 feet deep with
100 feet of drifts on the Bullpup claim. By 1928 the mine had been re-
named the Permit and consisted of 2 claims, the Boulder and Permit,
owned by Theodore Kockel of Mariposa (Laizure, 1928, p. 110). In
1932 the mine was acquired by the Permit Mines, Inc. of Mariposa. At
that time the directors of the company were A. J. Walters, J. J. Fahn-
lender, Mabel R. Brocke and Theresa J. Thompson. More recently the
Permit Mining Company has been operated by E. B. Cook of San
Francisco and H. H. Odgers of Midpines. A small production was
recorded in the 1930s and again in the late 1940s. From 1898-1900,
a total of 241.87 oz. of gold was produced from the Bulldog and Bull-
pup claims. In 1912 the Kockel mine (Bulldog) produced 6.87 oz. of
gold from 28 tons of ore (U. S. Bureau of Mines records). The mill
is fully equipped and the mine is operated intermittently.
The main vein on the Permit property is on the same system that
extends from the Milburn mine north to the Nutmeg mine. At the
Permit mine it strikes N. 10-20° W., is nearly vertical and is 2-4 feet
wide. According to Laizure (1935, p. 40) there are two other more or
Xos. 1 and 2] mixes and mineral deposits, mariposa county 151

less parallel veins. He describes a west vein 3-4 feet wide, a center
vein 2 feet wide and an east vein 2 feet wide. In 1935 there was a
70-foot shaft on the west vein, a 70-foot shaft with a 500-foot drift on%
the center vein and a 74-foot shaft on the east vein. At that time ore
averaged $15 to $20 a ton. The main vein observed by the authors ap-
parently is the center vein mentioned by Laizure. Wall rocks are py-
roxene andesite greenstones of unknown age. In 1954 the mine was
fully equipped with hoist house, compressor house and mill but there
was no one on the property and the equipment was not accessible.
Pine Tree and Josephine Mine. Location : Sees. 8, 9, 16, 17, T. 4 S.,
R. 17 E., M.D., on Highway 49, 2 miles north of Bear Valley. Owner-
ship : Pacific Mining Company, Crocker Building, San Francisco, Cali-
fornia, owns about 5^ square miles of the northern end of the former
Las Mariposas Grant which includes the Pine Tree and Josephine,
French, Evans and Queen Specimen mines.
History : Along with the Princeton and Mariposa mines the Pine
Tree and Josephine mine is among the best known and most chronicled
in the southern part of the Sierran gold belt. Conspicuously located
astride Highway 49 overlooking the Merced River it has a prominence
and background of historical romance equalled by few other gold mines.
The Pine Tree and Josephine vein system was discovered in 1849,
probably soon after discovery of lode-gold at the Mariposa mine. Orig-
inally separate mines, the Pine Tree and Josephine have been worked
jointly for so long that they have emerged as a single property.
The original locators and operators of the mine, whose names have
been forgotten, lost their rights and title to the Pine Tree and Jose-

phine mines through a court decision in 1859 giving John C. Fremont
control of the vast Las Mariposas Grant of 44,387 acres. In spite of the
court decision an armed struggle for possession of the mines took place
in 1859 and Fremont's followers were actually besieged on the fortified
Pine Tree property by miners then in possession of the Josephine mine.
Fremont ultimately gained undisputed possession of all the grant
mines, but his management was never very successful. Logan states:
"the grant properties became subject to one promotion scheme after
another and comparatively little gold was produced (considering the
possibilities) until 1900. . . ." In 1862 a disastrous flood damaged
many of the grant mines. In 1863 a group of Fremont's creditors in
New York formed a stock company capitalized for $10,000,000 but this
company went into receivership in 1864. In spite of the financial vicis-
situdes of Las Mariposas Grant at large, the Pine Tree and Jose-
phine mines operated almost continuously through the 1860s to about
1875. The elaborate Benton mill with its much publicized Ryerson
process of dry-milling and steam-activated amalgamation, was built
about 1865 just south of the present town of Bagby on the Merced
River. This was ultimately enlarged to 80 stamps (Raymond, 1871,
p. 28). In 1873 the Mariposa Land and Mining Company succeeded
the former Mariposa Company. Under this management a long tunnel
was driven south on the vein which ultimately reached a length of
3300 feet and extended under the Queen Specimen mine workings to
a depth of- 1200 feet. It was the intention of the company to extend
this tunnel clear to Mariposa, a distance of 12 miles, but the ore shoots

encountered proved disappointing and the strength of the company
was gradually dissipated in litigation and internal disputes. The grant
was finally purchased at sheriff's sale by a man named Donahue. In
July 1887, the present Mariposa Commercial and Mining Company
was organized by San Francisco financiers headed by Hayward, Flood,
Hobart, Jones and Mackey, who bought the grant from Donahue. This
group engaged in little or no mining and little was done at the Pine
Tree and Josephine mine until after 1898 when the company was
reorganized with Fred Bradley as president. Sustained mining began
about 1900 and was successfully continued until about 1915, about a
third of a million dollars being produced from the Pine Tree and Jose-
phine property. Another period of inactivity ended in 1933 with
acquisition of the northern end of the grant by Pacific Mining Com-
pany. Between 1933 and 1944 this company operated continuously and
achieved by far the greatest production ever realized by the mine.
Operations ceased because of wartime conditions and the mine has
never resumed production because of high operating costs. The prop-
erty is by no means exhausted of ore and simply awaits more favorable
economic conditions.
Geology: The Pine Tree and Josephine mine workings follow ore
shoots in various parts of a single, immense, multiple-vein system, the
Mother Lode here averaging at least 125 feet wide. It strikes N. 30-35°
W. and dips 55-60° northeast. In general the vein system occupies a
thrust fault of large displacement bordered on the east by serpentine
and on the west by the Mariposa slate. Both of these rock units are
believed to be of Upper Jurassic age. A typical cross section of the
154 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
Mother Lode in the Pine Tree workings is in the vicinity of the No. 2
East and No. 3 West crosscuts on the level of the New Pine Tree
Tunnel (see Logan, 1935, p. 188). Southwest to northeast across this
section the character of the vein is as follows :
P'ootwall side — black Mariposa slate thickness unknown
Josephine "vein" — quartz lenses and stringers in brecciated slate with ore
shoots 18 feet
Massive carbonate rock — ankerite — mariposite-quartz rock probably de-
rived by replacement of serpentine 60 "
Old Pine Tree "vein" — ribbon quartz with ore shoots (largely stoped) 10 "
Milky (bull) quartz — massive, barren of ore or low-grade 12 "
Hanging Wall Pine Tree vein — ribbon quartz with ore shoots 8—14 "
Serpentine and talc schist 10 "
Greenstone or metadiorite 25 "
Hanging wall side — serpentine thickness unknown
One version of the structure of the Mother Lode at the Pine Tree
and Josephine mine to a depth of about 1200 feet is shown facing page
108 of Julihn and Horton (1940). In the ore shoots ore minerals are
chiefly pyrite, arsenopyrite, and native gold with minor chalcopyrite,
sphalerite, galena, niccolite and millerite. Copper has been the only
metal recovered other than gold or silver. The nickel content of the
concentrates ranges from 0.35 to 1.35 percent and during 1936 averaged
0.77 percent (Julihn and Horton, 1940, p. 110). Erythrite and danaite,
both containing cobalt, have been found in the mine but presumably
are rare and well disseminated. Thus far there has been no attempt
to recover the nickel or cobalt.
According to Storms (1900, p. 144), the Old Pine Tree and Jose-
phine veins in the southern parts of the Josephine mine are very close
together — in places less than an inch apart, whereas they diverge to
the north and are 60 feet or more apart. The Mother Lode pinches
materially between the Pine Tree mine and Bagby as well as to the
south toward Bear Valley. Between Bear Valley and Mt. Bullion the
Mother Lode is represented by several en echelon veins rather than by
a single wide multiple vein. The northeast-trending veins represented
by the French and Lucky Boy veins do not intersect the Mother Lode
in the vicinity of the Pine Tree and Josephine mine.
Workings: The workings of the Pine Tree and Josephine mine are
connected by a single raise driven, during the last stages of operation,
from the Pine Tree Tunnel level to the English Trail Tunnel level
of the Josephine mine. The April adit in the Pine Tree mine and the
September adit in the Josephine mine are only about 200 feet apart
and at approximately the same elevation. The River Tunnel extends
under the Queen Specimen mine and if extended would connect with
main (MacKenzie) underground shaft in the Pine Tree workings theo-
retically at the 1150-level. The accompanying diagram shows the disposi-
tion of the workings.
The most southerly working is the McMurray shaft, about 60 feet
deep which has no lateral workings of note. The Josephine workings
begin with the Josephine and the Hunt and Oyler adits about 550
feet north of the McMurray Shaft, the last about 275 feet above
the Josephine adit. Connecting with the Josephine adit is the Septem-
ber adit, nearly 1200 feet farther north, and there are three others,
the No. 1, No. 2 and English Trail in between. A winze from the
Josephine adit has 3 levels, the 100, 300 and 500 and there is one drift
Nos. 1 and 2] mines and mineral deposits, mariposa county 155
level (the Black drift) between the Josephine and Hunt and Oyler adits
connected by winzes. The total depth developed on the vein in the
Josephine workings is 820 feet and the total length of workings is about
7700 feet. The principal ore shoot is developed for at least 600 feet.
The Pine Tree workings consist of 7 adits spread over a distance
of about 1500 feet. The principal working is the New Pine Tree adit
about 1200 feet long and the inclined MacKenzie shaft sunk from the
New Pine Tree adit approximately 600 feet from the portal. The
MacKenzie shaft serves levels at 150, 270, 430, 550, 700 and 850 feet
and there are 3 levels above the New Pine tree adit at depths of about
150, 200 and 250 from the surface. The workings aggregate over 8 miles.
Summary of Production : The estimated production of the Pine Tree
and Josephine mine is over $4,000,000 (Bradley, 1954, p. 32) and the
recorded production is about $3,386,000. Prior to acquisition by Fre-
mont no production records are available, due chiefly to secrecy con-
nected with disputes and the final litigation. Between 1860 and 1863
forty-five thousand tons of ore was mined which yielded $350,000, an
average of $7.77 per ton (Logan, 1935, p. 187, quoting Browne). In 1864
production was $67,940. For the fiscal year ending in July 1870 the
Mariposa and Pine Tree and Josephine mines yielded $170,000 of which
nearly $100,000 (Browne, 1868, p. 30) must have come from the Pine
Tree and Josephine. No records are available for the period 1865 to
1875 but the yield must have been substantial. Little or no mining was
done between 1875 and 1900. From 1900 to 1915 the production was
$371,748 from 20,968 tons of ore for an average of $12.40 per ton.
Between 1933 and 1937 production was $989,174 from 170,943 tons
of ore or an average of $5.78 per ton, and $271,392 was produced from
55,021 tons of ore in 1938 (Pacific Mining Co. records). From 1939
to 1944 a total of 248,481 tons of ore yielded 35,215 oz. of gold, and
8219 oz. of silver for a gross of about $1,242,000, an average of $5.00
per ton.
Princeton, New Princeton and Princeton Extension. Location : Sees.
13, 18, T. 5 S., R. 18 E., M.D., at the southern outskirts of Mt. Bullion
on the paved Mt. Bullion-Cathay road. Ownership : Mariposa Commer-
cial and Mining Company, c/o Eileen Milburn, Mariposa, California
owns a tract of land containing several hundred acres that includes
the Princeton and several adjoining mines. Formerly part of Las
Mariposas Grant.
The Princeton mine was discovered in 1852 (Browne, 1867, p. 29)
and has had a history similar to other large mines of Las Mariposas
Grant (see Mariposa and Pine Tree and Josephine). It has the greatest
recorded production of any mine in Mariposa County and the size of
the workings is exceeded only by the Pine Tree and Josephine mine.
At various times it has been the largest producer in the state. During
the early years of its history the ore yielded about $70 per ton, to a
depth of about 100 feet, but the bulk of the ore mined ran between
$4 and $7 per ton at the old price of gold. By 1867 it had reached a
depth of 560 feet as measured on the incline, and had been explored
along the strike for 1200 feet (Browne, 1867, p. 41-42; 1868, p. 30).
The New Princeton mine, adjacent to the Princeton to the southeast
was discovered and developed between 1871 and 1875 (Raymond, 1871,
p. 30). Two inclined shafts were sunk on this location 200 feet apart.

According to Knopf (1929, p. 84) a shaft 300 feet deep was sunk at
the New Princeton between 1921 and 1924. It had levels at 150 and
300 feet.
Between 1875 and 1900 the mine lay idle but mining was resumed
and vigorously pursued between 1900 and 1911 under the direction of
John H. MacKenzie. The shaft was deepened to 1600 feet (inclined)
and lateral workings greatly expanded. During this period most of
the ore in the main shoot was stoped to a depth of 1200 feet (Lowell,
1916, p. 595). A small tonnage of ore was mined in 1915 after which
the mine again lay idle until 1921. That year T. E. Kelso and W. H.
Holmes contracted to purchase the Princeton mine and held the prop-
erty until 1927 when a forest fire destroyed the surface buildings
(Laizure, 1928, p. 111). Soon after this the property reverted to the
Mariposa Commercial and Mining Company. Under Kelso and Holmes
3944 tons of ore was mined which averaged about $3.16 per ton at the
old price of gold. W. J. Loring was their superintendent in 1924.
Lessees produced a small tonnage of high-grade ore in 1930-31 and
3828 tons of ore and tailings were milled between 1935 and 1941, but
no sustained mining has been carried on at the Princeton mine since
1927.
The Princeton vein, believed to be part of the Mother Lode system,
occupies a thrust-fault fissure cutting slate of the Upper Jurassic Mari-
posa formation. The slate contains thin beds of dark-colored graywacke
and is cut by dikes of sheared, fine-grained granitic porphyry. Some of
these interesect the vein. The trace of the vein is not well defined at the
surface and lacks the massive, multiple characteristics of the Mother
Lode at the Pine Tree and Josephine and Mount Ophir mines. The
vein is en echelon to the vein passing through the Mount Ophir but is
more or less in line with the veins passing through the Greens Gulch,
Louis and Mountain View mines. It is probable that the Mother Lode
in this vicinity consists of several separated veins rather than one or
two major persistent features. The Princeton vein system strikes N.
54-57° W. and dips 45 to 60° northeast, averaging perhaps 50°. Vein
matter, which is ribboned, milky quartz carrying numerous parallel
sheets of included wall-rock, varies from 4 to 8 feet wide. Parts of the
vein which constitute ore carry a considerable amount of pyrite. Native
gold is seldom visible but minor amounts of galena, sphalerite and tetra-
hedrite are commonly seen (Knopf, 1909, p. 85). At the New Princeton
workings the slate is severely bleached and hydrothermally altered near
the vein.
The main shaft of the Princeton mine, now caved and inaccessible, is
1600 feet deep, measured on the incline, and reaches a vertical depth
of about 1250 feet. It has 9 levels at 300, 500, 600, 800, 950, 1100, 1250,
1400 and 1600 feet. The longest level is the 800, approximating 2100
feet. There is a total footage of drifts approximating 11,500 feet to-
gether with over 3000 feet of crosscuts and raises. The old Phillips
shaft, about 350 feet southeast of the main shaft was approximately
600 feet deep. On the New Princeton part of the property the 6 x 10 ft.
main shaft (east shaft) is 300 feet deep and has levels at 100 and 300
feet. The west shaft is 60 feet deep. The New Princeton shaft was open
to a depth of about 75 feet in August 1955.
There are various estimates as to the total production of the Prince-
ton mine. A total of $4,397,743 is well authenticated. Storms (1900, p.
158 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
143) conservatively estimated the production to 1900 at $3,000,000 and
production since that time has been $1,397,743, calculated from records
of the Mariposa Commercial Mining Company and U. S. Bureau of
Mines. Raymond (1871, pp. 30-31) places the early production at
$4,000,000 \o $5,000,000 and Knopf (1929, p. 84) places the total pro-
duction to 1929 at $5,000,000. The mine has been characteristically one
of large ore bodies of relatively low grade, although the characteristic
ore mined prior to 1915 would yield $10.50 per ton at the present price
of gold.
Pyramid (Castagnetto I) Mine. Location: Sees. 14, 15, 23, T. 4 S.,
R. 16 E., M.D., on the west bank of Cotton Creek half a mile from the
paved Hunter Valley road or about 9^ miles from Hornitos. Owner-
ship : Lloyd A. Mason, Hornitos, California owns about 200 acres of
patented agricultural land which includes the Pyramid mine.
The Pyramid mine was discovered prior to 1900, probably by Daniel
Castagnetto. It was operated for a time in 1915-16 by C. H. Burt and
Dodge of Bear Valley (Castello, 1921, p. 110). In 1925 the mine was
purchased from the Castagnetto estate by George K. Allen of Piedmont
(Laizure, 1928, p. 83). A mill was installed and some development
work was done but there was no sustained production. In the middle
1930s it was operated by the Pyramid Gold Mining Company in which
Eugene B. Gratton of San Jose and Lloyd Mason of Hornitos were
the principal officers (Julihn and Horton, 1940, p. 121). From 1933 to
1942 a total of 5117 tons of ore was mined from which 4062.33 oz. of
gold and 544 oz. of silver were taken for an average lvalue of $27.86
per ton. The total production of the mine must be at least $200,000.
At the surface the main vein at the Pyramid mine strikes N. 60-65°
W. and dips 45-71° southwest. According to Julihn and Horton (1940,
p. 121) the vein steepens to 80° within 190 feet of the surface. Vein
matter is mainly milky quartz with a little white calcite and includes
leaves and fragments of wall rock. Ore minerals are native gold, pyrite,
galena and sphalerite. About 95 percent of the gold is free-milling.
Sulfide concentrates amount to only \ percent of the ore (Julihn and
Horton, 1940, p. 121) but contain 5 to 6 oz. of gold per ton. Wall rocks
are chiefly pyroxene andesite greenstones belonging to the Upper Juras-
sic Amador group with thin strata of tuffaceous slate. Julihn and
Horton (1940, p. 121) state that diorite forms the hanging wall of the
mine, but no diorite was seen by the authors at the surface and none
was on the dumps. A narrower parallel vein has been worked to some
extent about 600 feet south of the main shaft.
Workings consist of four shafts two of which apparently have not
been used since early days. The main working in the 1930s was a 6 x 10
foot shaft 190 feet deep with three levels at 65, 105 and 175 feet. From
this shaft there is a 90-foot north drift and a 240-foot south drift ; 238
feet of drift north and 85 feet south on the 105-foot level and 215 feet
of north drift on the 176-foot level (Julihn and Horton, 1940, p. 121).
A second shaft is 165 feet deep, but the uepths of the others are not
known. None were accessible to the authors in August 1954. The com-
pressor hoist and hoist had been damaged because of sliding ground.
The 5-stamp mill appeared to be in fair condition. No recent work has
been done at the property.

The mine is entered by several adits, openings of which are not
shown in the photo. Mine workings were being put into condition for
operation during 1955. The Quail mine has a long record of produc-
tivity extending back prior to 1873 and totaling over $400,000.
Quail (Alvina, Hartford) Mine. Location : Sees. 15, 16, T. 3 S., R.
17 E., M. D., on the north side of Indian Gulch about 7 miles by fair
dirt road southeast of Greeley Hill. Accessible via McDiermid guard
station and Date Flat. Ownership: H. E. Moerlien, San Martin, Cali-
fornia owns four patented lode claims, the Juniper, Sunset, Bonanza
and Mammoth, 7 unpatented claims, the Violet, Starlight, Morn Sight,
Fairview, and West Lode 1, 2 and 3, plus several mill sites aggregating
over 380 acres.
The Quail mine was discovered prior to 1873 and has a total produc-
tion estimated at slightly more than $400,000 ( Julihn and Horton, 1940,
p. 140). The first owners of record were Hanbidge and Gonigall who
made a strike of good ore in 1873 (Min. and Sci. Press, vol. 26, No. 10.
p. 149, 1873). These operators had driven at least one tunnel by 1873
and were in process of driving a raise for ventilation. By 1891 owner-
ship had passed to Francisco Bruschi and considerable production was
maintained. Ore was said to average $15 per ton in native gold and
sulfide concentrates ran $800-$900 per ton (Min. and Sci. Press, vol. 62,
no. 12, p. 180; vol. 62, no. 18, p. 276). Various members of the Bruschi
family operated the property intermittently through the 1890s. In
1899 the property was bonded for a short time to Kendall Brothers and
Whitney at which time the working tunnel was 700 feet long and an 18-
inch wide shoot of ore was being mined. Later in 1899 the mine was
sold by D. Bruschi to the Quail Mining and Milling Company, a group
160 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
made up of Sonora, California, businessmen (Min. and Sci. Press, vol.
78, no. 18, p. 488; vol. 78, no. 21, p. 565). A 4-stamp mill was moved
onto the property from the Louisiana mine and it was renamed the
Hartford mine in 1900. The Engineering and Mining Journal, vol. 68,
no. 12, p. 293, 1899, states that the mine included 3 tunnels, one 800
feet long', one 1300 feet long, and the third of unstated length, and
that an ore shoot 2\ feet wide was yielding ore running $20 per ton.
Between 1899 and 1901 a small production of gold was recorded
that }^ear. Operations were carried on through 2 working tunnels and
4 raises. The vein varied between 18 and 60 inches wide and ore aver-
aged $7.50 per ton at the old price of gold (Eng. and Min. Jour., vol.
71, no. 9, p. 283, 1901). There is no record of activity at the mine be-
tween 1901 to 1915. Various lessees worked the property under agree-
ment with the Bruschi Brothers between 1915 and 1920. Some ore was
milled which ran between $9 and $12 per ton at the prevailing price of
gold (Castello, 1921, p. 134). A 10-stamp mill was destroyed by fire
in 1917. Castello states that the workings, in 1920, consisted of a tunnel
about 1000 feet long, two shafts 150 feet and 55 feet deep, respectively,
and several stopes and raises. In 1915 one of these stopes was reported
to be 200 feet long and 70 feet high (Lowell, 1916, p. 595). Between
1920 and 1935 the mine lay idle until reactivated late in 1935 by J. E.
King and associates of Sonora. About 1937 the property was purchased
from J. Bruschi by Quail Gold Mines, Inc., Jerome L. Drumheller of
Spokane, Washington, in charge and Otto D. Rohlfs of Coulterville,
general manager. Between 1937 and 1942 a total of 7161 tons of ore was
milled which yielded 444 oz. of gold and 394 oz. of silver or an average
of approximately $2.22 per ton. Again idle through the war years, the
Quail mine was leased in 1949 from Jerome Drumheller by the Golden
State Mining Company, a partnership of George Marshall, Clarence and
Stanley Silvia and H. E. Moerlien. More recently ownership has passed
to H. E. Moerlien of San Martin, California, who has been retimbering
two adits and preparing to reopen the mine. A fully equipped 60-ton
per-day capacity mill is on the property which includes jaw crushers,
ball mill, shaking tables, flotation cells, etc.
The principal vein at the Quail mine strikes N. 20-25° W. and dips
30-35° NE as it passes through the Juniper, Mammoth and Bonanza
claims, but swings to a north strike as it crosses the Sunset claim. The
width varies between 18 inches and 5 feet. According to Julihn and
Horton (1940, p. 140) the vein fissure has been intruded over much
of its length by and aplite dike about 2 feet wide which at some places
follows the footwall side of the vein and at others the hanging wall.
Vein matter consists of milky quartz with pyrite, galena, sphalerite,
tetrahedrite and native gold. Wall rocks consist of mottled slate, sandy
slate and associated schistose metasediments belonging to the Paleozoic
Calaveras group. The slate cleavage in the upper adit strikes N. 40° W.
and dips 75-80° NE.
The principal operating workings are two adits, one 90 feet vertically
above the other. The lower adit is 700 feet long and the upper one 550
feet. These probably have not been reopened the full length of former
workings. The upper tunnel is connected with the surface by a 135-foot
raise 200 feet from the portal of the adit and the lower adit is con-
nected to the surface by a 328-foot raise 300 feet from the adit portal.

These raises were in need of cleaning out in August. 1954. The adits
had been newly re-timbered and were in good condition.
Queen Specimen Mine. Location : Sec. 8, T. 4 S., R. 17 E., M. D., on
Highway 49 a quarter of a mile north of the Pine Tree mine buildings,
3 miles north of Bear Valley and 1 mile south of Bagby on the Merced
River. Ownership : Pacific Mining Company, 1022 Crocker Building,
San Francisco, California, owns a large acreage of the former Las
Mariposas Grant, which includes the Queen Specimen, Pine Tree and
Josephine, French and Evans mines.
The Queen Specimen mine has a history more or less parallel to the
Pine Tree and Josephine mine which it adjoins on the northwest (see
Pine Tree and Josephine mine). It was discovered in the 1850s and
worked in a small way prior to acquisition of Las Mariposas Grant in
1859 by Fremont. It was worked by the Mariposa Mining and Com-
mercial Company in 1908 and in 1915, producing a total of 657.5 tons
of ore yielding $6029.22 or a total of $9.16 per ton at the old price of
gold (Logan, 1935, chart facing p. 188). During the period 1922-1924
the mine was operated under lease from the Mariposa Commercial and
Mining Company. In this period 3000 tons of ore was milled which
yielded $4 per ton and an undisclosed quantity of tailings which carried
$2.50 per ton (Knopf, 1929, p. 84). Little has been done at the prop-
erty since 1924 and the workings are caved and inaccessible.
The multiple vein on the Queen Specimen property is the northwest-
ern extension of the Mother Lode as seen at the Pine Tree and Josephine
mine. It has a general strike of N. 35° W., and dips 60-70° northeast
and has an aggregate thickness of about 105 feet. Ore occurs almost
entirely on the footwall side, varying between a few feet and 12 feet
thick and yielding $4 to $12 per ton (Knopf, 1929, p. 84). Knopf de-
scribes the cross section along the main adit SW to NE as follows ■
1. serpentine — 130 feet
2. black slate— 370 feet
3. quartz— 3-12 feet
4. ankerite-quartz-mariposite rock netting with quartz veinlets — 15 feet
5. talc schist (derived from serpentine) — 30 feet
6. greenstone (locally called diorite, hydrothermally altered, pyritized and
sheared — 48 feet
7. black slate — extent not measured
The ore shoot was 1-1J feet thick on the footwall side of the quartz
member of the vein system. Primary minerals in the ore shoots are
native gold, pyrite, tetrahedrite and chalcopyrite, probably with minor
amounts of additional minerals similar to those at the Pine Tree and
Josephine mine. Joints in the quartz member of the vein system were
described by Knopf as being stained by azurite in some places.
Mine workings in 1924 consisted of: (1) A main 500-foot crosscut
adit, driven northeast approximately perpendicular to the strike of the
vein system, a connecting main drift 400 feet long and a raise with
levels at 100 and 125 feet above the adit level. (2) An upper adit
driven 200 feet (vertically) above the main adit connected with a 250-
foot drift. (3) A lower crosscut adit, about 500 feet north of the upper
adit, with minor drifts. (4) A 150-foot drift adit and stope about 400
feet northwest of the lower crosscut adit. None of these workings were
accessible in September 1955.

Bed Bank (Stevenson group) Mine. Location : Sec. 36, T. 3 S.
R. 16 E., M.D., on the northeast bank of the Merced River 1^ miles
northwest of Bagby. Accessible via half a mile of unimproved dirt road
from Highway 49, the turnoff being 1 J miles from Bagby. Ownership :
Percy L. Pettigrew, Box 639, Palo Alto, California, and Horace Meyer,
Cathay, California, own the Daisy, Jubilee and Syndicate lode claims
and three placer claims totaling about 165 acres. Most of this holding is
patented.
The Red Bank mine was probably discovered in the late 1860s. Most
of the early work done consisted of placering and ground sluicing. In
1881 hydraulic mining was started under Colonel Swadley (Min. and
Sci. Press, vol. 43, no. 26, p. 429, 1881) but from the looks of the prop-
erty no great yardage of material was handled in this way. The first
extensive underground mining was done between 1894 and 1897 by the
Redbanks Mining Company under Isaac Solhinger (Min. and Sci. Press,
vol. 71, pp. 106, 138, 238). Two tunnels aggregating 400 feet were
driven but the vein apparently was not reached. In 1897 the owners,
Henry Bratnoble and A. Wartenweiler optioned the mine to Hamilton
Smith and associates at an agreed purchase price of $100,000. This deal
apparently was not consummated and the property was then bonded to
the London Exploration Company. The Daisy tunnel was extended by
this company to a total length of 900 feet, striking the vein about 1000
feet below its outcrop (Min. and Sci Press, vol. 75, pp. 30, 170, 434,
598). The vein was found to be 30 feet wide with ore assaying about
$10 per ton. The mine closed down in 1898 before any considerable
production was realized, apparently because of lease and ownership
disputes. Some rehabilitation and development work was done on the
mine in 1910, 1914, 1915, and 1917-18. E. C. Loftus of San Francisco
had purchased the mine in 1906 (Eng. and Min. Jour., vol. 82, no. 11,
p. 513, 1906), a French syndicate held the property in 1910 and own-
ership had passed to H. C. Callahan of San Francisco by 1914. A small
tonnage of ore was milled between 1917 and 1918, ten tons of ore yield-
ing 28 oz. of gold and 40 oz. of silver (U. S. Bureau of Mines records).
A 5-stamp mill, separating tables and flotation were employed (Min.
and Sci. Press, vol. 114, p. 104, 1917). By 1920 ownership had passed
to Percy L. Pettigrew and H. C. Callahan, the mine being idle that
year. By 1928 Percy L. Pettigrew had become the sole owner (Castello,
1921, p. 135; Laizure, 1928, p. 113). No mining was done in the 1920s
but in 1935 the mine was leased by F. W. Draper. By 1937 a large
tonnage of ore had been blocked and a 125-ton mill was being installed
(Eng. and Min. Jour., vol. 140, no. 1, p. 70, 1937). During 1939 and
1940 a total of 12,796 tons of ore was milled which yielded 1551 oz. of
gold and 6894 oz. of silver worth about $62,000 — an average of about
$4.74 per ton (U. S. Bureau of Mines records). The total production
of the mine is well in excess of $100,000.
The Red Bank mine develops two well-defined veins belonging to the
Mother Lode system, the Crown Peak and the Stevenson, as well as sev-
eral smaller mineralized shear zones. These veins have a general strike
of N. 40-45° W. and dip northeast at angles between 50 and 60 degrees.
The Crown Peak vein over much of its length follows the fault contact
between serpentine and Mariposa slate. The Anderson vein, on the foot-
wall side of the Crown Peak vein, in most places is in slate. Vein matter
Nos. 1 and 2] mines and mineral deposits, mariposa county 163
in the Crown Peak vein commonly is 30 feet thick with ore-bearing
parts averaging about 7 feet thick. Milky quartz, quartz-mariposite-
ankerite rock and rusty silica-carbonate rock are the usual vein-rock
types. The Anderson vein is similar to the Crown Peak but, in general,
not so well defined or so thick. Ore minerals are pyrite, argentiferous
galena and native gold with minor tetrahedrite, chalcopyrite and
sphalerite. Ore milled in 1939-40 carried an unusually high percentage
of silver for a Mother Lode mine.
The Red Bank mine has been developed chiefly by crosscut adits that
explore the vein for more than 2400 feet of strike length and an in-
clined depth of over 1000 feet. Because of curvatures in the vein the
roughly perpendicular crosscuts are not mutually parallel but trend
north or northeast. The Daisy and Stevenson adits give access to the
most extensive workings. The workings may be summarized as follows,
west to east :

Red Cloud (Kate Kearney) Mine. Location: Sees. 22, 27, T. 2 S.,
R. 17 E., M.D., on Bear Creek 3J airline miles east of Greeley Hill or
10 miles east of Coulterville. Accessible by unimproved dirt road by
way of the McDiermid guard station of the U. S. Forest Service.
Ownership: Carl Harper, Coulterville, California, owns one claim of
approximately 20 acres.
The Red Cloud mine was discovered prior to 1880 but the principal
period of operation was 1885-1895 when most of the workings were
driven and most of the production made. Castello (1921, p. 135)
reports the estimated production to be about $1,500,000 but there are
no records to substantiate this claim. In 1885 the mine was owned by
Gaines and Carter of San Jose, California (Min. and Sci. Press, vol.
51, no. 7, p. 120, 1885). J. S. Carter was mine manager and R. B.
Harper and John Guest were superintendents at various times under
Carter. The shaft was down 360 feet late in 1885, was deepened in
1886 to 430 feet and again in 1893 to 700 feet. A 22-stamp mill was
operating on the property in 1889 but fell idle soon thereafter, steam-
powered. The operator in the middle 1890s was the Red Cloud Mining
Company of Boston. Two short ore shoots were followed down to the
500 level during operation by Gaines and Carter, but these were
lost between the 600 and 700 levels and the Red Mill Mining Company
was reported to have spent $60,000 in fruitless exploration between the
600 and 700 levels (Min. and Sci. Press, vol. 80, no. 11, p. 265, 1900).
In 1900 the property was optioned to A. P. Dron of Big Oak Flat
but was not put into production. The owner in 1904 was Mrs. E.
Whitman of Coulterville (Wilkinson, 1904, p. 13). By 1920 ownership
164 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
of the mine had passed to Mrs. Emma McDiermid of Coulterville who
retained possession of the mine throughout the 1920s. In 1935 the mine
was leased for a short time by Fredericks and Hodge of Mariposa.
The authors know of no active mining at the property since 1935.
The vein at the Red Cloud Mine strikes N. 40° E. and dips 60-80°
north. Wall rocks are slaty metasediments of the Paleozoic Calaveras
group. The vein averages about 5 feet wide, locally reaching a width
of 15 feet. Vein matter is milky quartz with inclusions of brecciated
wall rocks, locally banded or ribboned. Two ore shoots each about
400 feet long were worked in the upper levels to a depth of over 500
feet, ore being 3-5 feet thick. In the middle 1880s ore was running
about $30 per ton mostly from native gold. The average content of
sulfides was about 2^ percent, auriferous pyrite concentrates running
between $100 and $200 per ton (Goodyear, 1888, p. 346). The vein is
traceable for a distance of more than 4500 feet and the original prop-
erty consisted of 3 claims oriented end to end on the main vein and a
4th claim near the east end of the vein at approximately right angles
to the main vein. Apparently an intersecting or cutter vein was located
in the workings which does not show at the surface.
Mine workings consist of a 8xl0-foot inclined shaft 700 feet deep
with levels at intervals of 100 feet. Most of the stoping has been done
above the 500-foot level. Drifts aggregate more than 500 feet. The
workings were all caved and inaccessible in October 1954.
Roma (Piedra de Goza) Mine. Location: Sec. 14, T. 4 S., R. 18 E.,
\\ miles south and slightly east of Briceburg. Accessible by less than
a quarter of a mile of trail from the Yosemite All Year Highway.
Ownership : Frank and Nellie Harris, 595 Tunnel Avenue, San Fran-
cisco 24, California, own a patented property containing 25 acres.
The Roma mine was discovered in the 1850s or early 1860s by Spanish
Californians and was known in the early clays as the Piedra de Goza.
Nothing concerning the early production of the mine has been recorded
but the early workings were extensive and a substantial early produc-
tion is probable. After lying idle for nearly 30 years the Roma mine
was reopened in 1897 by the Holiday Mining Company directed by
T. J. Parsons, G. W. Baker, J. Jacobs et al. with C. G. Rogers as super-
intendent (Eng. and Min. Jour., vol. 63, no. 7, p. 168). Several tunnels
were opened. A 24-foot vein was struck in the longest of these at a
depth of 250 feet from the surface. The mine apparently was idle
much of the time in 1898 and 1899 but in 1900 a long tunnel (adit)
was started designed to strike the intersection of the Roma and
Sierra Rica veins at a point 1400 from the adit portal (Eng. and Min.
Jour. vol. 70, no. 6, p. 107, 1900). The Roma and Sierra Rica mines
at this time were operated jointly by the same management (Storms,
1900, p. 146). By September 1, 1900,* this adit had reached a length of
915 feet and ultimately reached 1000 feet. Its cross-sectional dimen-
sions are 5 by 7 feet and it reached a depth of 600 feet below the
outcrop of the Roma vein. Lewis Anbury superintended this operation.
Very little work has been done on the mine since 1901. In 1904 the
owner was listed as C. Kerrins of Mariposa (Wilkinson, 1904, p. 13).
Later ownership passed to Matt Harris and has been held by various
members of the Harris family up to the present time.

Photo taken from beside the Hornitos-Mt. Bullion road with the
observer facing south. The main Ruth Pierce vein extends across
the hilltop from side to side of the photo and is well exposed where
it crosses the road to the left of the photo. About $600,000 has been
taken from this mine.
The main vein at the Roma mine averages 2 to 2J feet wide locally
thickening to as much as 5 feet. It strikes slightly north of east, dips
60-70° S. and is a continuation of the vein crossing the adjacent King
Solomon claim. The wall rocks are massive pyroxene andesite green-
stones of unknown age. Adjacent to the vein there has been rendered
slaty to schistose by intense shearing.
Rutherford and Cranberry (Perrin and Craigue) Mine. Location :
Sees. 15, 22, T. 3 S., R. 19 E., M.D., just north of the Merced River
and Highway 140, 4 miles by road west and slightly south of El Portal.
Ownership : L. G. Goodrich, 1522 State St., Santa Barbara, California,
owns a fractional claim, the Rutherford, containing 10.34 acres. Owner-
ship of other claims of the Rutherford and Cranberry group were not
determined.
The Rutherford and Cranberry mines are contiguous properties
operated throughout much of their history under the same management.
The Rutherford mine, closest to the Merced River, was discovered about
1863, probably by the Rutherford brothers. As early as 1865 there was
a water-powered, 5-stamp mill on the Rutherford mill site (Min. and
Sci. Press, vol. 10, no. 11, p. 163, 1865). According to Castello (1921,
p. 112) the Cranberry mine, situated high on the hill north of the
Rutherford mine, was discovered in 1863 and patented in 1873. The
Rutherford mine was patented in 1874 (Laizure, 1928, p. 114). In 1867
166 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
a 50-foot shaft was sunk to connect with one of the tunnels. At that
time ore ran $40 per ton as well as other miscellaneous workings. In
1868 the Rutherfords sold the properties to undisclosed individuals
from San Francisco. By 1875 ownership was held by Perrin and
Craigue with S. W. Craigue acting as mine superintendent. The mines
were intermittently active until the summer of 1880 when the mine
was closed down because of disputes among the owners. In 1879 ore
was averaging about $10 per ton, but occasional masses of ore were
found that ran as high as $4500 per ton. The principal owners in 1884
were Capt. A. H. Ward and S. W. Craigue. These individuals con-
structed 2 water-powered arrastras and considerable rich ore was taken
from the Rutherford mine from a depth of about 70 feet. In 1885 a
rich ore shoot was discovered in the Cranberry mine in a new crosscut
driven about 500 feet southeast of the main shaft and on the opposite
side of the ridge at a depth of 100 feet below the vein outcrop. At the
time of the new discovery, the two arrastras each were milling 1 ton
of rock per day which returned $34.60 per ton, mainly from ore taken
from the old Cranberry shaft (Mill, and Sei. Press, vol. 51, no. 14, p.
232, 1885). The vein encountered was described as 11 feet wide and
very rich, but no statement as to the tenor of the ore was made.
Mining on the Rutherford property apparently was discontinued for
a long period and effort was concentrated at the Cranberry mine. By
1888 the new ore-shoot had been developed for a length of 400 feet
and a vertical depth of 320 feet by shaft and winze. The ore-shoot was
described as 4 feet wide (Goodyear, 1888, p. 348; Storms, 1896, p.
217). Mining continued until about 1896 after which the property lay
idle until 1927. A. H. Ward held ownership until the middle 1920s
when the property passed into the hands of P. E. Bass of San Fran-
cisco. During that year Bass leased the property to R. A. Frederick of
El Portal and considerable drifting was done on the Rutherford vein
(Laizure, 1928, p. 114). There is no record of production for this pe-
riod. About 1935 the property was leased by Yosemite National Gold
Mines Company, John C. McGarry, manager (Laiznre, 1935, p. 43). A
new 200-foot shaft was sunk and considerable drifting done on the
200-level. In July, 1954, there was a good cabin on the Rutherford
property, but no equipment, and the mine workings were inaccessible
because of minor caving.
Although no production records are available for the Rutherford and
Cranberry group of mines the total yield must have been impressive.
The lowest grade of ore mined apparently ran about $10 per ton at
the old price of gold and Laizure (1928, p. 114) states that several
shoots averaged $20 per ton. Much ore ran considerably higher, par-
ticularly in the upper 100 feet of the veins where the ore was oxidized
and enriched through removal of sulfides. Pyrite concentrates assayed
$35 to $40 per ton in the late 1880s (Goodyear, 1889, p. 348). There
is no indication that the veins were worked out and the total depth
reached, about 320 feet, does not adequately explore the veins en-
countered on either the Rutherford or Cranberry properties.
There are two sets of veins at the Rutherford mine, one striking N.
10-15° E. and dipping 75-80° west and the other striking about N.
75-80° E., and nearly vertical. Some work has been done on at least
four north-trending veins and one or more veins trending nearly east.
Wall rocks are coarse-grained biotite granodiorite or quartz diorite cut
Nos. 1 and 2] mines and mineral deposits, mariposa county 167
by narrow dikes of fine-grained hornblendic quartz diorite. Vein matter
is milky quartz with native gold, pyrite, arsenopyrite and galena. Pyrite
makes up about 25 percent of the ore below the zone of oxidation (Good-
year, 1888, p. 349). The main vein is 1 foot to 5 feet wide averaging
3 to 4 feet. Others are thinner and less persistent along the strike.
Workings at the Rutherford property consist of a main drift adit
with connecting shaft, a 200-foot shaft with workings on the 200-level
and several less extensive adits. None of these were accessible to the
authors in July, 1954. The shaft connecting with the main adit (located
a short distance northwest of the cabin) has one level between the
shaft collar and the haulage adit and both levels are connected to ex-
tensive stopes. The adit was 460 feet long in 1921 (Castello, p. 136).
The 200-foot shaft sunk in 1935 could not be identified in July 1954
and presumably is caved at the collar.
At the Cranberry mine, about half a mile north and slightly west of
the Rutherford mine workings, the main vein strikes roughly N. 50°
IT. and dips northeast at 40-50°. It averages 4 or 5 feet wide locally
reaching widths of 11 feet. The vein cuts coarse-grained granitic rocks
containing small pendants of dark slate, schist and hornfels. Topogra-
phy is exceedingly rugged. Workings include 3 drift adits, all over
200 feet long and the longest at least 700 feet. The long tunnel con-
nects with an 80-foot shaft (Castello, 1921, p. 136). Storms (1896, p.
217) also mentions a connecting 200-foot shaft 500 feet from the adit
portal. There is a crosscut adit 500 feet southeast of the old shaft on
the opposite (east) side of the ridge which cuts the vein at a depth of
100 feet below the outcrop (Min. and Sci. Press, vol. 51, no. 14, p. 232,
1885). This connects with extensive drifts and stopes. All of these
workings are partially obscured by cave-ins and none had been entered
recently in July 1954.
Schoolhouse Mine. Location : Center sec. 10, T. 4 S., R. 16 E., M.D.,
in the central part of Hunter Valley about 7 airline miles northeast of
Hornitos. Accessible via the paved Hornitos-Bear Valley and Hunter
Valley roads. Ownership : Frank A. Maschio and John Maschio, Merced,
California, and Joe Maschio, Snelling, California own one patented
claim, a part of the patented Maschio Ranch.
The Schoolhouse mine is an old property which had extensive work-
ings and dumps prior to 1912. During 1912 and 1913 the property was
operated under bond by G. P. Gow of Berkeley with W. Taylor acting
as superintendent (Eng. and Min. Jour., vol. 94, no. 21, p. 1002; vol.
95, no. 21, p. 1071). A 2-stamp mill was placed in operation crushing
ore from old dumps. About 1916 some work was done by Milton Suther-
land of Atwater, but soon closed because of disputes. The mine was re-
opened by Sutherland in 1923 and some very rich ore was taken out
from 2 levels (Laizure, 1928, p. 115) between 1923 and 1925. A small
production was recorded in 1931 (IT. S. Bureau of Mines records) since
when there has been little or no activity at the mine.
Mine workings are along the southeast extension of a prominent vein
system locally known as the Blue Lead, which strikes N. 30-35° W. and
dips about 60° E. The vein system cuts pyroxene andesite greenstone
containing bands of red chert, these rocks belonging to the Upper
Jurassic Amador group. Gold occurs in pockets in dark, bluish quartz.
The principal working is a 60-foot inclined shaft serving two levels of

undetermined length but the shaft is caved and the headframe has
been removed. A blacksmith shop remains on the property. There had
been no recent activity in June 1954.
Schroeder (Home) Group. Location: Sec. 16, T. 4 S., R. 18 E.,
M.D., on high ground west of Saxon Creek Canyon 3 airline miles
northwest of Colorado School and 6^ airline miles north of Mari-
posa. Accessible by 2\ miles of unimproved dirt road from the graded
Saxon Creek-Sherlock Creek road. Ownership : C. M. and R. E. Schroe-
der, Box 169, Mariposa, California own the patented Schroeder placer
claim of 20 acres and 8 other unpatented claims including the Home,
Rex, Missing Link, New Deal, Caldwell, Apex, Independence and
Nelly Bly claims.
The Schroeder group of claims was discovered in the late 1870s or
early 1880s by John Schroeder. The first sustained mining apparently
began about January 1883 with hydraulicking and ground sluicing of
soil and the upper weathered parts of the veins. Numerous sizeable nug-
gets and a great deal of fine gold was recovered, enough to finance
construction of a ditch and pipeline as well as other miscellaneous
equipment. In June 1883 the county was engaged in surveying for a
pipeline designed to insure an adequate water supply for hydraulick-
ing operations at the Schroeder and adjacent Schantz mines (Min. and
Sci. Press, vol. 46, no. 22, p. 372, 1883). By May 1886 hydraulicking and
ground sluicing operations had laid bare a blanket vein dipping 30-
35° to the east (Min. and Sci. Press, vol. 52, no. 18, p. 288, 1886) as
well as several other veins, and it became necessary to explore the
property underground. During the middle 1890s the mine was sold
to F. W. Keeney of San Francisco, J. A. Schroeder remaining as super-
intendent. A new mill was erected about this time. By April 1898 the
mine had been bonded to W. Price who recovered a piece of ore weigh-
ing 13 pounds which yielded $2,000 (Min. and Sci. Press, vol. 76. no.
16, p. 422, April 16, 1898). Storms (1896, p. 223) describes the veins
as pockety. Nevertheless 483.75 oz. of gold were produced from the
mine during 1896 from an undisclosed quantity of ore (U. S. Bureau
of Mines records). Between 1900 and 1906 approximately 133 tons of
ore was mined which yielded 595.51 oz. of gold and 12 oz. of silver for
an average of approximately $90 per ton.
In 1915 the mine was being operated bv J. A. and C. J. Schroeder,
P. W. Judkins and C. H. Weston ( Lowell," 1916, p. 596). They installed
a 5-foot, 20-ton Huntington mill. At that time the principal working
was an open cut 200 feet long and 30 feet deep, but about 375 feet of
drifts had been driven. By 1920 the open cut had been enlarged to
400 feet long and 60 feet deep. At present it can hardly be recognized
from other gulches in the vicinity.
The Schroeders, Judkins and Weston retained ownership of the prop-
erty through the 1920s but did very little work on it. In 1932 some
production was recorded, apparently by the Schroeders and in Janu-
ary 1934 the mine was taken lease by Ashworth and Pehrson of Mari-
posa (Laizure, 1935, p. 44). Ownership has remained largely in the
Schroeder family to the present time and there has been a substantial
intermittent production of ore averaging slightly over 1 oz. of gold
per ton. In the fall of 1954 intermittent mining was being carried on
from a northwest-trending adit about 150 feet above and southwest of
Xos. 1 and 2] mines and mineral deposits, mariposa county 169
the mill but there was no one on the property at the time of the authors'
visit.
Recorded production of the Schroeder group of mines since 1896 is
$158,400 as calculated from U. S. Bureau of Mines records. Inasmuch
as this does not include the very substantial production of the 1880s
and early 1890s the total production of the group must be between
$200,000 and $300,000.
By far the greatest production from the Schroeder group of mines
has been from residual soil mantle and from the weathered, f ragmental
upper parts of the several veins which cut the property. A system of
relatively narrow, more or less parallel, north-trending veins crosses
the property. Most of these veins have a very steep east dip. Cutting
this system is a somewhat discontinuous blanket-vein varying from a
few inches to 3 feet wide. This dips east at angles varying from 15° to
nearly 35°. Wall rocks are massive, schistose and slaty pyroxene an de-
site greenstones derived partly from tuff and partly from massive flows
and dikes. The greenstones are of probable Paleozoic age. The schistosity
of the greenstone, where well developed, strikes N. 60° W. and dips
very steeply southwest.
In 1935 the principal working was an adit 215 feet long and a 15°
inclined shaft 35 feet deep (Laizure, 1928, p. 44). In August 1954 there
was a long adit driven southwest (N. 60° E.) from a point just west of
the mill building and at the same level as the building. There are sev-
eral adits of various lengths higher up the ridge from this lower adit
that trend N. 30-40° W. The lower adit was not in active use, most
of the current development work being done on the upper adit located
nearest a small cabin or tool shed. This was not entered, in the absence
of the owners, but was at least 150 feet long.
The mill includes a 5-foot diameter, 20-ton capacity Huntington
crusher and appeared to be in running condition. There is also a serv-
iceable compressor and compressor house and other miscellaneous mine
buildings.
Silver Lead (St. Gabriel and Honeycomb, Silver Lead and Marga-
retta) Mine. Location: Sec. 28, T. 4 S., R. 16 E., M.D., 4J miles north
and slightly east of Hornitos. Accessible by li miles of unimproved dirt
road from the paved Hornitos-Bear Valley road. Ownership: E. G.
Branson, et al., c/o Horace Meyer, Cathay, California owns two pat-
ented claims the Silver Lead and Margaretta totaling 39.84 acres. Prop-
erty originally included the St. Gabriel and Honeycomb claims but
these may have been re-named.
The Silver Lead mine was first discovered in the 1860s (Castello,
1921, p. 138) but was only active at wide intervals up to 1914. In
1880 some work was done at the mine by A.S.F. Company (Min.
and Sci. Pres, vol. 40, no. 23, p. 357, 1880) but there is no record
of production. In 1901 it was bonded for a short time to Richard
O'Brien. In 1914 the property was acquired by the Mariposa Min-
ing and Milling Company of Carson City, Nevada, with W. A. Bradley
acting as mine superintendent (Lowell, 1916, p. 597). At that time
Lowell reported the workings to consist of a 240-foot shaft with 422
feet of drifts. Bradley put a 5-stamp mill into operation and a moderate
production of medium and low-grade ore was recorded. About 1919 the
management was reorganized under the name Simpson Mining Com-
170 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
pany, W. A. Bradley remaining as superintendent, but this company
ceased operations in 1922 (Laizure, 1928, p. 117). About 1935 the St.
Gabriel and Honeycomb claims were taken under lease by the Sanchez
Brothers of Hornitos (Laizure, 1935, p. 45) and there was some pro-
duction by lessees up to 1947. There was no activity and no equipment
at the property in July 1954.
Ore occurs in a narrow vein of glassy to milky quartz accompanied
by a zone of quartz stringers 2-4 feet wide. The mineralized zone strikes
about N. 30° W. and dips 40-45° northeast. Wall rocks are chiefly dense,
massive, blue-black quartz-biotite hornfels and massive spotted slate.
These apparently are cut at depth by green metavolcanic dikes and
dark, quartz-rich granodiorite porphyry dikes. None of these crop out
conspicuously at the surface. Both the metasediments and intrusives
are of Upper Jurassic age. Ore minerals, in addition to finely divided
native gold, include pyrite, chalcopyrite, galena, sphalerite, and arseno-
pyrite. The silver content is no greater than most other gold ores of
the Sierran foothill belt. Ore milled during the later periods of mining
yielded $4-7 per ton. The principal working at the Silver Lead mine
is an inclined shaft at least 250 feet deep serving 2 or 3 levels. This was
flooded to within 50 feet of the collar in August 1954. In 1928 there
were two levels aggregating about 500 feet (Laizure, 1928, p. 138).
There are several short tunnels and shallow shafts and pits in a line
extending northwest for about a quarter of a mile. The tunnel workings
are both sides of a ravine which cuts across the trend of the vein
system.
Spread Eagle Group (Farmers Hope, Miners Hope, Empire, Mohawk,
Monarch, Fanny, Little Charlie, Tollgate, Bonanza). Location: Sees.
29, 31, 32, T. 4 S., R. 18 E., M.D., near the Whitlock Creek-Sherlock
Creek road 4 airline miles north and slightly west of Mariposa. Acces-
sible from State Highway 49 via 5 miles of graded dirt road and half
a mile of unimproved dirt road. Ownership : Mack C. Lake, c/o Carlo
S. Morbio, 58 Sutter St., San Francisco, California owns a property
patented in 1934 which includes the Empire, Fanny, Little Charlie,
Miners Hope (Farmers Hope), Mohawk, Monarch, Spread Eagle and
Tollgate claims and the Empire millsite, a total of about 100 acres.
The Spread Eagle group of mines was discovered between 1850 and
1860 as an aftermath of placer-mining on Whitlock Creek (Julihn and
Horton, 1940, p. 148). They are a consolidation of numerous claims
separately owned in early days but gradually consolidated under one
ownership. In 1896 the Farmers Hope (later called the Miners Hope)
was owned by J. J. Ellingham and in 1903 by Ellingham and Grove —
operated under bond to E. Waters and Sons who had a 5-stamp mill.
The Farmers Hope was also extensively developed in 1905 by Stolder
and Dussel, presumably under lease or bond, in conjunction with an
adjoining claim called the Bonanza.
The Spread Eagle mine was operated in the late 1890s and early
1900s by Jacob Teats (also spelled Teets). Teats bought and installed
a 2-stamp mill on the claim in the summer of 1904 (Eng. and Min.
Jour., vol. 75, no. 3, p. 102, 1903). In August 1904 the Spread Eagle
mine was under lease to Nevills and Hanna who took out 28 tons of
ore which yielded $120 per ton (Eng. and Min. Jour., vol. 78, no. 5,
p. 197, 1904).
Nos. 1 and 2] mines and mineral deposits, mariposa county 171
By 1915 ownership of the Farmers Hope group of seven lode and two
placer claims and one millsite had passed to G. L. Kennedy of Mariposa,
and Nick Mullins of Whitlock held two claims under the name Spread
Eagle mine (Lowell, 1916, p. 582, 597). At that time the Farmers Hope
group was inactive and the Spread Eagle was active under lease. On
January 1, 1916 the Farmers Hope claim was relocated by Nick Mullins
and renamed the Miners Hope, assessment work having been allowed
to lapse on the Farmers Hope group of claims (Castello, 1921, p. 126) ;
Mullins held both the Miners Hope and Spread Eagle groups of claims
until 1927 when they were reported sold to Belle McCord Roberts of
Long Beach (Consolidated Gold Fields of Mariposa, Laizure, 1928, p.
117), but little or no mining was done under this ownership.
In the spring of 1934 the Spread Eagle — Miners Hope group of mines
was reopened by Whitlock Mines Corporation under the management
of Martin Tresidder and a 5-stamp mill was put into operation (Laiz-
ure, 1935, p. 38). The Whitlock company and later a leasing partner-
ship of Martin Tresidder and R. C. Poor made a substantial production
from the property between 1934 and 1939 from ore running slightly
less than a quarter of an ounce of gold per ton (U. S. Bureau of Mines
records). There has been no recorded production from the mines since
1939.
The following discussion on the geology and mine workings is drawn
chiefly from Julihn and Horton (1940, pp. 148-150) the last authors
to visit the mines while they were in operation. "The principal work-
ings are on two nearly parallel veins that strike almost due north but
diverge at depth. The Spread Eagle dips about 45° E., and the Miners
Hope, which outcrops 600 to 700 feet to the west of it, dips about 60°
E. . . ! The average width of the Spread Eagle vein is about 20
inches but in stoped areas it has been considerably wider, up to a
maximum of 7 feet. Both walls are greenstone. The ore consists of
quartz carrying gold, pyrite, chalcopyrite and occasional galena, the
sulfides composing about 1 percent of it. Above the adit level, which
corresponds closely with the water level, the ore was almost wholly
free-milling, while below it about one-fourth of the gold is contained
in sulfides, the concentrates from which average about $250 per ton.
The ore mined above the adit level averaged about 1 ounce of gold
per ton, but the vein contained frequent pockets of high-grade, and 2-
and 3-ounce ore was not exceptional. It is of interest that ore shoots
were found at two places where the vein bends sharply to the east. . . . "
"The early workings of the Miners Hope included numerous deep
trenches, shallow pits, and adits extending over 1000 feet along the vein
but principally within 600 feet of the northern end of the claim. There
the vein is said to have averaged over 4 feet in width for at least 300
feet, attaining a maximum width of 12 feet in one stope. South of this
section, however, its width was 14 inches to 2 feet. The vein follows
rather closely the contact of a schist (schistose greenstone) on the foot-
wall and greenstone on the hanging wall. . . . The ore shoots are said to
have been associated with small fissures coming through the schist to
an abutment with the greenstone. Some of these fissures contained a
fine-grained dike rock.

In the Empire claim south of the Miners Hope, is a small vein called
the Dolph, which is said to have produced $25,000. It lies about 100
feet east of the southern extension of the Miners Hope vein and dips
70° E. The Mohawk claim contains the northerly extension of the Whit-
lock vein, one of the famous early producers of the district. ' '
The principal workings on the Spread Eagle vein are a 5- x 8-foot
inclined shaft 345 feet deep, intersected by an adit at a depth of 125
feet (as measured along the dip of the vein). A drift driven at adit
level both ways from the shaft is about 1000 feet long and has about
150 feet of auxiliary workings. There are about 1250 feet of drifts
below the adit level. The upper part of the shaft is caved and most of
the other workings were in need of cleaning out in August 1954.
On the Miners Hope vein the most recently used important working
is a 2-compartment inclined shaft 328 feet deep as measured on the
dip. It connects with an east-driven crosscut adit striking the vein at
an inclined depth of 133 feet. These workings are about 800 feet from
the north endline of the Miners Hope claim. The shaft has drift levels
at 138, 190 and 308 feet (see accompanying plan and section). The
133-foot level extends more than 200 feet north and 200 feet south of
the shaft but in 1939 was caved beyond these distances both north and
south. Nearly all of the ore encountered above the 138-level has been
mined. The 190-foot level extends north of the shaft 85 feet and 367 feet
to the south. The 308 foot level consists of a 133-foot north drift and a
188-foot south drift. Neither the 190- nor 308-levels reached the region
of stoping done from the 133-level north of the shaft, although the
308-level was within 100 feet of the stoped area in 1939 (Julihn and
Horton, 1940, p. 150). According to these authors only about half of
the ore between the 133- and 308-levels north of the shaft has been
stoped. In 1937 an ore shoot 90 feet long was discovered on the 308-foot
level and this was mined up to the 133-foot level. Its length decreased
rapidly above the 190-foot level. Twenty-five hundred tons of ore was
produced from this shoot which carried about $9.70 per ton, but only
$7.20 was recovered by amalgamation. Seven-tenths of one percent
of the ore from this shoot was auriferous pyrite sampling about 10 oz.
of gold per ton of concentrate, on the average. Unfortunately the con-
centrates were lost in a storm.
Up to 1940 the best available information gathered by Julihn and
Horton indicated the total production of the mines now included under
the Spread Eagle group (including the Empire and Fanny mines) to
be $42^,000. No further production has been recorded since that time.
Production reported to the U. S. Bureau of Mines for the period 1893
to 1955 aggregates approximately $100,200 in gold and silver. A small
amount of copper was recovered in 1914 from the Spread Eagle mine.
The ore milled before 1934 averaged a little over half an ounce of gold
per ton and that mined in the 1930s ran approximately 0.26 oz. of
gold per ton.

placer claim.
The Sweetwater mine was discovered prior to 1884 but has been
worked intermittently at widely spaced intervals. In 1903 the owners
were E. J. and L. E. Hanchett with J. W. Jones as superintendent. A
new 10-stamp mill was put into operation in 1905 but no production
was recorded for the period 1903-1905. In 1914 the mine was reopened
and developed by a man named McAllister. Two tons of selected ore
mined by McAllister yielded 9 oz. of gold and 4 oz. of silver (U. S.
Bureau of Mines records). In 1917 the mine was sold to E. C. Gamble
and W. S. Stewart of Oakland who did some exploration but no sus-
tained mining. By 1919 it had passed into the hands of the Dominican
Mining Syndicate Inc., Coalinga, California (H. L. Schultz, Pres.) with
M. Gamble acting as superintendent. The 10-stamp mill was overhauled
(Castello, 1921, p. 118) but little or no production was realized from
the mine. By 1928 the mine had been acquired by C. A. McCartney of
Jerseydale who sold it that year to Frank Zuhosch and associates of
San Francisco (Laizure, 1928, p. 118). Late in 1933 the property
passed to the present owners. Between 1934 and 1937 approximately
300 tons of ore was milled which yielded 70 oz. of gold and 189 oz.
of silver (U. S. Bureau of Mines records). Lee Rowland leased the mine
in 1941 and 1942 and took out 32 oz. of gold and 6 oz. of silver from
9 tons of hand-picked ore. The mine was being operated under lease
to Clyde Foster in the fall of 1954.
The Sweetwater vein averages close to 3 feet thick, strikes N. 55° W.
and dips 13° to 27° near the surface. According to Castello (1921,
p. 118) the vein dips 45° at depth. The thickness of the vein is very
irregular and the ore is pockety. Vein matter is mainly glassy to milky
quartz with native gold and pyrite. Concentrates produced in 1934-37
ran from $148 to $112 per ton, the tonnage of ore represented not
being recorded (U. S. Bureau of Mines records). Wall rocks are coarse-
grained, hornblende granodiorite or quartz diorite strongly weathered
to depths as great as 50 feet. Much of the soil mantle above the vein
is gold-bearing but the considerable clay content makes this ground
difficult to handle. Some placer-mining has been done on the soil
mantle. Pendants of slate probably belonging to the Paleozoic Calaveras
group crop out northwest of the mine workings.
At present the mine is entered by a 600-foot crosscut adit which con-
nects with a 350-foot southeast drift and an 800-foot northwest drift.
There is an old inclined shaft 170 feet deep with a 123-foot level which
was caved and not in use in August 1954. The drifts from the adit level
had not been wholly cleaned out by the present operator in August
1954. There are also several extensive stopes which have not been re-
cently explored. There is part of a 10-stamp milling installation on the
property which might be rehabilitated.
The production record for the Sweetwater mine is fragmental and no
reliable estimate can be made. Most of the ore appears to have been
mined prior to 1903 but the ore mined since that time has been of con-
siderably better than average grade.
Texas Hill (Carrie Todd, Texas) Mine. Location: Sees. 7, 8, T. 3 S.,
R. 18 E., M.D., high on the east wall of the North Fork of the Merced
Nos. 1 and 2] mines and mineral deposits, mariposa county 175
River Canyon 2 miles southwest of Kinsley guard station of the U. S.
Forest Service. Accessible from either Briceburg or Coulterville by way
of the graded Kinsley road and 2| miles of unimproved dirt road (Pon-
derosa Way). Ownership: G. Ross Frank and Mary E. Shell, c/o W. J.
Beatty, Coulterville, California own the patented Carrie Todd claim of
20.66 acres and several adjoining unpatented claims.
The Texas Hill mine, first called the Texas mine and later the Carrie
Todd was discovered about 1865 and produced intermittently in a small
way up to the 1900s. In 1882 Francisco Bruschi bonded the property
to Gilbert Douglass of Seth Cook and Company (Min. and Sci. Press,
vol. 45, no. 26, p. 405, 1882) but no great amount of work was done at
that time. It passed into the hands of Mrs. Hannah Douglass and re-
mained under her ownership until the middle 1920s. A small produc-
tion, presumably by leasers, was recorded in 1912-15. In 1919 the prop-
erty was under bond to Milton Fraser of Kinsley and Mr. Sain of
Coulterville who were in process of constructing a 10-stamp mill (Cas-
tello, 1921, p. 110) . Estelle I. Fraser and George Frank of Coulterville ac-
quired the mine in the middle 1920s. In 1927 the property was taken
over for a short time by the Gentry Gulch Consolidated Mines Company
of San Francisco, Thomas I. Box, president (Laizure, 1928, p. 82). In
March 1934, the Texas Hill Mining Company of San Francisco, P. J.
McLaughlin, president, leased the mine and operated it until about
1937. Leasers operating under ownership of G. D. Frank worked the
mine from 1941 to 1943 since when the property has been inactive.
The known production of the mine is about $74,000 (McLean, W. D.,
personal communication, 1956). Ore produced in 1941-43 averaged
about a third of an ounce of gold and a fifth of an ounce of silver per
ton, plus a little copper and lead. Prior to that time the ore had run
approximately $20.00 per ton based on the present price of gold.
The principal (Carrie Todd) vein at the Texas Hill mine averages
2-4 feet wide, strikes roughly east and dips 70-75° north. There are at
least two minor parallel veins on the property developed by superficial
workings. The veins cut dark slate and quartz-biotite hornfels probably
belonging to the Paleozoic Calaveras group of metasediments. The Car-
rie Todd vein is developed by three drift adits each several hundred
feet long. A winze connects the lower and middle tunnels (No. 2 and
No. 3). The most recent work apparently was done from the No. 2
tunnel. Ore shoots are about 150 feet long and average about 2 feet thick.
Tyro (Bittershoffen) Mine. Location: Sees. 9, 10, T. 3 S., R. 16 E.,
M.D., 1^ airline miles southwest of Coulterville. Accessible by 1^ miles
of dirt road via the Malvina mine. Ownership : Louise A. AVard and
Laurence Eaton, P. O. Box 223, Ross, Marin County, California own
one patented claim of 20.15 acres.
The Tyro mine was probably discovered in the early 1850s at about
the same time as the Malvina group. Although there were some workings
prior to 1889, most of the development work and mining was done by
the Tyro Mining and Milling Company under the management of
Charles Sutherland and J. McLaughlin. The company was incorporated
in 1889 (Eng. and Min. Jour., vol. 47, no. 20, p. 462, 1889). By 1895
the inclined shaft had reached the 600-level and drifts were being
run on the 500-level (Eng. and Min. Jour., vol. 60, no. 6, p. 132). The
shaft was deepened to the 700-foot level in 1896 and by the end of
176 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
1897 more than 1870 feet of drifts had been run. The company operated
a 10-stamp mill. There were several changes of management during the
late 1890s and the mine fell idle for several years. In 1902 and 1903
Thomas J. Brown operated the mine and rehabilitated the mill but no
sustained mining was done (Eng. and Min. Jour., vol. 73, no. 15, p. 530;
vol. 76, no. 15, p. 54). In 1909, McClure Gregory operated the mine for
a short time but management again reverted to Joseph Buttgenback, a
former president of the Tyro Mining and Milling Company, later that
year. There has been little or no production from the mine since 1897.
The workings were inaccessible and there was no equipment on the
property in September 1954. The estimated production from 1893 to
1897 was $110,000 (Logan, 1935, p. 190).
Both the Tyro and the Malvina group of mines are on the west branch
of the Mother Lode, the vein system at the Tyro mine being a continua-
tion of the one that crosses the Malvina group of claims. It strikes
about N. 20° W. on the Rittershoffen claim and dips from 60 to 70°
northeast. Vein matter is largely milky quartz 2 to 7 feet wide. Ore
shoots generally occur in a ribbon structure of quartz interleaved with
thin sheets of wall rock (Fairbanks, 1890, p. 39). In addition to finely
divided native gold there is considerable auriferous pyrite and chal-
copyrite. Fairbanks also mentions the presence of covellite. The prin-
cipal ore shoot was found between the 600- and 700-foot levels. This was
at least 80 feet long and more than 100 feet deep. Most of the ore on
the 700-foot level ran $20 per ton at the old price of gold and some ran
as high as $500 per ton (Min. and Sci. Press, vol. 72, no. 13, p. 250;
vol. 73, no. 11, p. 222).
The principal workings are an inclined shaft 700 feet deep with 6
levels and about 1870 feet of drifts (Logan, 1935, p. 190). Most of the
ore has been stoped between the 600 and 700 levels in the main ore shoot
and there has been considerable near-surface stoping, particularly north
of the main shaft. In September 1954 this shaft was open to a depth of
about 70 feet and there were several openings into the near-surface
stopes. One of these may have been an old shaft. There has been no
recent activity at the mine.
Virginia (Yirginia-Belmont, White Gulch, Captain Aiken) Mine.
Location: Sees. 13, 14, T. 3 S., R. 16 E., M. D., just west of Highway
49 about 4 miles south of Coulterville. Accessible from Highway 49 by a
quarter of a mile of unimproved dirt road. Ownership : Sam E. Wells,
7533 Cecilia Ave., Downey, California, owns a patented property of 72
acres which includes the Virginia No. 2, Belmont, Claremont, Angus
and Piedmont claims. Once included the Coe Gulch placer claim.
History: The Virginia mine was discovered by a group of miners in
1850 but was not extensively developed by them. Through the 1860s it
was owned by Captain el. M. Aiken and was known as the Captain
Aiken mine. Late in 1879 it was acquired by Senator Coe of New York.
Coe and Lewis White sunk a shaft and drove a connecting adit during
the winter of 1879-1880 and were reported to have taken out enough ore
to pay for the mine (Min. and Sci. Press, vol. 39, no. 26, p. 413, 1879).
During 35 days of mill operation during the spring of 1880 over $20,000
was recovered, and one pocket of specimen ore containing large flakes
and stringers of gold yielded $10,000 (Min. and Sci. Press, vol. 40, no.
23, p. 357, 1880). The mine apparently remained under operation of
Nos. 1 and 2] mines and mineral deposits, mariposa county 177
Coe until about 1884. Production under Coe is supposed to have been
$100,000 (Min. and Sci. Press, vol. 75, no. 16, p. 366). The property
fell idle between 1884 and 1888 but late in 1888 was bonded to Colonel
Cook of Big Oak Flat, representing eastern interests. Cook unwatered
and explored the mine but decided against reopening (Min. and Sci.
Press, vol. 57, no. 18, p. 292, 1888). In 1894 the owner was listed as the
Virginia Mining Company of Springfield, Ohio. Between 1894 and 1896
the property was described as in litigation (Storms, 1896, p. 224) but
was leased, for a short time in 1895 to McKenzie, Hoxie and Donahoe.
Late in 1895 the litigation apparently was settled and O 'Toole and
Arnold of San Diego emerged as owners — at a purchase price reported
to be only $5,000 (Storms, 1896, p. 224; Min. and Sci. Press, vol. 75,
no. 76, p. 366, 1897). In January 1896 a find of rich ore was reported.
Later that year the mine was bonded to Paul Blackmar and the well
known Clarence King, and was reactivated under the direction of J. J.
Dolan in the summer of 1896 (Eng. and Min. Jour., vol. 62, no. 2, p. 36,
1899). This management was short lived and on January 1, 1897 the
property was bonded by the California Exploration Company, Ltd.
from O 'Toole and placed under the superintendency of R. A. Parker.
This company completed a 10-stamp mill and made considerable produc-
tion before ceasing operations in the summer of 1898 because of a
shortage of water. At that time the shaft was 470 feet deep and ore was
milling $5.50 to $10 per ton (various issues of Min. and Sci. press).
In 1904 O 'Toole operated the property under the name Virginia Gold
Mining Company and produced 1000 tons of ore which returned about
0.74 oz. of gold per ton (U. S. Bureau of Mines records). In October
1907 the property was transferred to Garnett and Priest of Kansas City
and T. W. McLean of Boise City, Idaho, McLean acting as mine man-
ager. About 2000 tons of low grade ore were produced by the manage-
ment but the operation again ended in litigation. S. E. Lewis of the
Crown Lead mine leased the property for a time in 1912 hut no produc-
tion was recorded. In the spring of 1913 the mine was acquired by the
White Gulch Mining Company of Oakland, a subsidiary of the Procter
and Gamble Company (Min. and Sci. Press, vol. 95, no. 16, p. 826, 1913 ;
Logan, 1935, p. 190). It was cleaned out and placed in operation under
the direction of C. C. Powning of Oakland. Extensive development and
production followed. By 1918 this company had deepened the shaft to
more than 700 feet and water became a serious problem for the first
time. Mining, however, was continued to a depth of 1000 feet and a
large tonnage of ore was milled which averaged slightly more than 0.4
of an oz. of gold per ton. The White Gulch Mining Company ceased op-
erations in 1920 and the Virginia Belmont Mining Company was
organized in Nevada to continue operations on the deeper levels of the
mine. W. V. Wilson was mine superintendent and B. C. Austin the
consulting engineer for this company. This enterprise lasted until May,
1923, the shaft having been deepened to 1050 feet. Early in 1927 an un-
successful attempt to reopen the mine was made by a group known as
the Virginia Lode Mines Company, but in November of the same year
the Nevada Hills Mining Company, Reorganized, of Reno, Nevada
(H. G. Humphrey, President), took over the property and did consider-
able rehabilitation and development work under the direction of F. B.
Hyder prior to the crash of 1929 (Min. and Sci. Press, vol. 127, no. 10,
p. 413, 1929). The workings were deepened to 1300 feet during this
178 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
period. In February 1932 the mine was reported sold to Fred Morris
of San Francisco but the only work done on the mine prior to 1934 was
by Grant Ewing. About 1035 tons of low grade ore was produced by
leasers between 1934 and 1936. During the period 1952-53 Sam E. Wells
and B. A. Miller drove a 450-foot exploratory tunnel on an old prospect
southeast of the principal mine workings which is believed to have pene-
trated to a point only 80 feet from the vein. A compressor, 10-stamp
mill and several mine buildings remain on the property (August 1954).
According to Logan (1935, p. 190) the total production of the
Virginia mine between 1898 and 1931 was more than $660,000. Inas-
much as production under Coe (1979-1884) was about $100,000 and
production since 1931 has been approximately $64,000 in gold and silver
(U. S. Bureau of Mines records) it follows that the total production of
the mine is at least $824,000 providing Logan's figures are correct.
U. S. Bureau of Mines figures for the period 1898 to 1931 show a pro-
duction of slightly less than half Logan 's figure but some of the produc-
tion may not have been reported.
The vein system at the Virginia mine is a segment of the east branch
of the Mother Lode system which in this vicinity strikes N. 50-55° W.
and dips 60° northeast, upon the average. Vein matter, which in places
reaches a thickness of 150 feet (Fairbanks, 1890, p. 41), is predomi-
nantly ankerite-quartz mariposite rock, more or less banded and altered.
The quartz sheets, in the vein near which the ore commonly is concen-
trated range from 8 inches to 4 feet wide. In addition to native gold,
ore minerals include pyrite, chalcopyrite and galena. For the most part,
the vein system follows the thrust-fault contact between serpentine,
which forms the southwest or footwall side, and pyroxene andesite
greenstone or mica schist on the northeast or hanging wall side. The
serpentine is believed to be of Upper Jurassic age, the greenstone is
either Jurassic or Paleozoic and the mica schist is part of the Paleozoic
Calaveras group of metasediments. The principal ore shoot found north-
west of the main shaft was mined down to 1200 feet and could not be
located on the 1300-level. It varied in length from 180 to 300 feet above
the 700-level, narrowed to 20 feet or less between the 700- and 1200-
levels and apparently had a nearly vertical axis. Ore shoot width
ranged from 8 inches to nearly 16 feet and averaged 3-4 feet. A second
smaller and less persistent ore shoot was mined southeast of the main
shaft.
Some bonanza ore was mined from the upper 80 feet of the vein, as
previously mentioned. Much of the ore in the vicinity of the 400-level
ran $15 per ton and $10 in the vicinity of the 300-level. On the 900-
level much of the ore mined in 1922 averaged $15 per ton. In 1918 ore
was reported to have averaged $17.50 per ton. In 1935, Logan stated
that most of the production was from ore that ran more than $10 per
ton. U. S. Bureau of Mines records indicate that the ore milled in 1904
averaged just under 0.74 oz. of gold per ton; in 1909 about 0.14 oz. of
gold per ton; in 1914 approximately 0.45 oz. of gold per ton; and in
the period 1919-1934, about 0.35 oz. of gold and 0.13 oz. of silver per
ton. Several hundred pounds of copper was also recovered, as a by-
product, in the early 1930s.
The principal working at the Virginia mine has been a 1300-foot in-
clined shaft, with levels at 100-foot intervals, and a connecting adit
Nos. 1 and 2] mines and mineral deposits, mariposa county 179
haulageway. The shaft is described as serving more than 10,000 feet
of drifts (Laiznre, 1928, p. 120). In addition to the shaft and adjoin-
ing" workings there are three old adits south of but in the general
vicinity of the main shaft, and a fourth crosscut adit (driven in
1952-53) 450 feet long which connects with an older working. The portal
of last adit is 1700 feet southeast of the main haulage way adit portal,
the mine buildings lying between these two localities. Most of the work-
ing could be entered in August, 1954 but undoubtedly are in need of
rehabilitation.
Washington (Jenny Lind, Bed Cloud) Mine. Location: Sees. 4, 5,
T. 5 S., R. 16 E., M.D., a quarter of a mile north of the paved Hornitos-
Bear Valley road and 2 miles northeast of Hornitos. Ownership : Pacific
Mining Company, Crocker Building, 620 Market St., San Francisco 4,
California, owns the patented Washington claim, containing 13.77
acres, and adjoining patented agricultural land aggregating 509 acres.
The Washington mine was discovered in 1850 and prior to 1900 was
probably the most productive mine among the many in the Hornitos
district. As early as 1851 it was equipped with a 6-stamp mill which,
for a time, produced 1000 oz. of gold per day! Except for a short
period between 1864 and 1868 operation was continuous from 1850 to
about 1882. In 1859 a 20-stamp mill was built on the Merced River to
serve the Washington mine. Much of the early work was done by the
Washington Mining Company in which George Webber and Moses L.
Rodgers were the principal partners. A 10-stamp mill was erected near
the Washington shaft in 1867 by this management. The mine was re-
ported to be 1400 feet deep in 1881 and to have been deepened to 1600
feet during that year (several entries in vols. 42 and 43 of the Mining
and Scientific Press), but was found to be a little less than 1500 feet
deep when reopened by the Lind Mining Company in 1941. Late in
1881 the property was reported purchased by Marcus and J. W.
Hulings of Pennsylvania, along with the Quartz Mountain, Number
Nine and numerous other mines in the Hornitos district. The Huling
venture proved unsuccessful and the Washington mine reverted to M. L.
Rodgers. Considerable development work was done by Rodgers in 1884
but the stock company under which Rodgers operated ceased to func-
tion in 1885. In 1896 it was announced that Rodgers had sold the mine
to S. W. Parker and associates of New York, the Hornitos Gold Mining
Company, and that further sale to an English company was being
negotiated. Nothing came of this transaction and the property re-
mained idle until reopened in 1903 by Harmon and Stevens (Jenny
Lind Mining Company), together with the Quartz Mountain mine.
Operations were directed by W. F. Stevens. This operation was also
short lived with little or no production realized. Several further at-
tempts were made to promote the mine, notably in 1900, 1910 and 1917.
In 1922 the owner was still listed as the Washington Mining Company.
The Cora Belle Mining Company took out a little high-grade ore in
1928 (U. S. Bureau of Mines records). The Mariposa- Washington
Mining Company of Hornitos built a new mill in 1939 and milled about
4000 tons of dump material between 1939 and 1940. By 1941 the
property had been acquired by the Lind Mining Company, a subsidiary
of the Pacific Mining Company, which took out a large tonnage of ore
of moderate grade between 1941 and 1942. The company reopened and

unwatered the caved Jenny Lind shaft, re-equipped the mine and did
extensive exploration and development work on the 700-, 800-, 1000-,
1100- and 1500-levels. The Jenny Lind shaft was deepened 36 feet to
a point slightly below the 1500-level. The 1000-level was cleaned out
to the Washington shaft which was found to be open between the 900-
and 1000-levels. A total of 7923 feet of workings were cleaned out or
newly driven between 1941 and 1942.
Between 1943 and 1945 the mill and flotation plant were leased by
Red Cloud Mines Company, a subsidiary of Hecla Mining Company of
Wallace, Idaho, to process complex zinc ore from the nearby Blue Moon
mine. Both mine and mill have been idle since 1945, reopening awaiting
more favorable economic conditions.
Prior to 1900 the Washington mine had an estimated production of
$2,247,000 and a recorded production of $1,099,000 (Bowen and Crip-
pen, 1948, p. 38). Between 1939 and 1942 a total of 17,356 tons of ore
was milled which yielded 3131 oz. of gold, 2436 oz. of silver, 1060 lbs. of
copper and 111 lbs. of lead for an average of about $6.35 per ton (U. S.
Bureau of Mines records). The total estimated production to 1954 is
$2,377,000. Bonanza ore was found in the upper parts of the vein but
most of the recent production has been from ore running between $6.50
and $7 per ton. According to Raymond (1875, p. 50), ore averaged
about $25 per ton, at a price of only $13 an ounce, in the middle 1870s.
The principal vein at the Washington mine strikes N. 40° W., dips
70-75° S.W. and averages 6 to 8 feet wide. Vein matter is chiefly
ankerite-quartz-mariposite rock in which large sheets and lenses of
Nos. 1 and 2] mines and mineral deposits, mariposa county 181
milky to glassy quartz several feet thick are locally developed. The
character of the vein closely resembles typical Mother Lode veins seen
7 miles farther east in Mariposa County. Ore minerals are chiefly pyrite
and chalcopyrite with native gold. In addition to the quartz vein-ore
there are, in places, masses of wall rock impregnated with auriferous
pyrite (gray ore). This material commonly runs 0.09 oz. of gold per ton.
Wall rocks are mainly micaceous and amphibole-bearing schists and
dark quartz-biotite hornfelses of Upper Jurassic age. According to
Storms (1896, p. 224) the vein is accompanied by a light-colored felsitic
dike which adjoins the vein on the footwall side in the southeast work-
ings and on the hanging wall side in the northwest workings. Small,
irregular intrusions of hornblendic granitic rock penetrate to the sur-
face west of the present mine buildings. Much of the metamorphic rock
seen in the vicinity of the shaft has been derived from platy, tuffaceous
metasediments.
The most recently used working entrance to the Washington mine
is the Jenny Lind shaft inclined at an angle of 68° and reaching a
depth of 1500 feet. It is surmounted by a lofty steel headframe and
the mill buildings are closely adjacent. The Jenny Lind shaft originally
had levels of 500, 600, 700, 1000, 1100, 1200, 1300 and 1400 feet but
the ground has been stoped and the levels largely destroyed between
depths of 500 and 700 feet. Approximately 670 feet northwest of the
'Jenny Lind shaft is the Washington shaft 1000 feet deep and inclined
at about the same angle as the Jenny Lind. This is open from the
surface to a depth of 1500 feet and is known to be open between 900-
and 1000-levels. Workings connecting with the Washington and Jenny
Lind shafts total nearly 2 miles.
About 200 feet north of the Washington shaft is the Franklin shaft,
200 feet deep, and 500 feet still farther north is a fourth old shaft
100-150 feet deep. There is a line of shallow workings between the two
old northwesterly shafts.
There is (August 1954) crushing, hoisting and milling equipment on
the property and there are several good mine buildings. A graded
dirt road connects with the paved Hornitos-Bear Valley road.
White Porphyry Group. Location : Sec. 34, T. 3 S., R. 17 E., M.D.,
in the Cat Town district 3 miles southeast of Buckhorn Peak or 1\
airline miles southeast of Coulterville. Accessible from Highway 49 by
way of the unimproved Buckhorn Peak-Solomon Gulch-Black Bart
road via the Schilling Ranch and Rybergs. Ownership: several of the
most northerly workings were being operated in September 1955 by
F. E. Ryberg, Coulterville. Ownership of the other claims could not be
determined.
The mile-long line of open stopes of the White-Porphyry group is
a conspicuous landmark southeast of Schilling Ranch and Buckhorn
Peak. It diagonally crosses section 34 on a gullied plateau. So far as
the authors were able to discover, nothing has ever been written about
these workings — extensive as they are. They undoubtedly date back to
the 1870s or before in the heyday of the Black Bart group mines lying
half a mile to the northeast.
Workings are arranged in two parallel lines along either wall of a
white albitite dike 30 to 50 feet thick traceable at the surface for over

a mile. This dike strikes N. 40-45° W. and dips 75° northeast. Wall
rocks are slate, schist and metachert of the Paleozoic Calaveras group.
Gold tends to occur in rust colored pockets in the albitite adjacent to
quartz stringers and to the enclosing slaty wall rocks, or in the quartz
stringers which cut both the albitite and the wall rocks close to the
contact. Ore apparently was confined to a narrow contact zone nowhere
over 6 or 7 feet wide and commonly only 3 feet wide. The average
depth of the open stopes is now only 30 to 40 feet but some caved
workings probably extended down over 100 feet. Horses of schist, slate
and metachert locally are caught in the albitite and some appear to
have been faborable places for concentration of ore.
No data are available on the production from this group of workings
but from the length and persistence of the stopes and the known high
grade of ore pockets in this district the yield must have been large.
The relative shallowness of the workings indicates that the best ore
was in the oxidized zone and may have been of considerably lower
grade at depth.
Whitlock Group (Consolidated Whitlock and Alabama). Location:
Sec. 32, T. 4 S., R. 18 E., M.D., east of the Whitlock Creek road 3J
airline miles northwest of Mariposa and 4J miles by graded dirt road
from Mt. Bullion on Highway 49. Ownership : Dr. Frank E. Gallison,
P. O. Box 491, Ventura, California, and E. J. Freethy, 1432 Kearney
St., El Cerrito, California, own 3 patented claims, the Westward, Ala-
bama and Whitlock, aggregating 47.68 acres.
The Whitlock group of mines was discovered prior to 1870, probably
in the 1850 's or 1860 's as an aftermath of placer-mining on Whitlock
Creek. In 1871 the property was transferred under option for $20,000,
to Stephens and Lamber (Min. and Sci. Press, vol. 22, no. 9, 1871).
Some production was made by this partnership that year and there was
intermittent activity at the mine by others, probably leasers, through
the 1870s. After a period of inactivity of several years' duration in the
early 1880s, the property was reopened or at least re-explored by Cap-
tain Diltz of the Diltz mine. At that time the ore was reported to aver-
age about $20 per ton and the vein to be 5 feet thick (Min. and Sci.
Press, vol. 46, no. 21, p. 256, 1883). During the early 1890s the mine
was owned and operated by the Ward Brothers. About 1895 the mine
was sold by Wards to the Sierra Buttes Gold Mining Company of
London, England, and most of the development work and sustained
mining at the property was done in the ensuing 5 years (Storms, 1896,
p. 24; Min. and Sci. Press, several issues 1892-1895). The Sierra Buttes
company erected a 20-stamp mill, replacing an earlier, smaller mill, and
maintained a steady production from 1895 to 1900. About $482,000
was recovered during this period. Mining ceased with "considerable
ore still in sight" because of the high operating costs (Castello, 1921,
p. 142). Jacob Teets was listed as the owner in 1904 (Williamson, p.
13) but by 1914 the property had passed into the Gallison family and
Lizzie Sain. A small production by Gallison and Sain was recorded be-
tween 1940 and 1942 when 942 tons of ore milled yielded only 133 oz.
of gold and 33 oz. of silver. Little or no work has been done on the
property since 1942. The total production of the mine is estimated to be
about $500,000.

stopes may be seen which are on the White Porphyry group of claims. Gold occurs
there in pockets along either wall of a 40-foot-wide albitite dike. The pockets are in
places found in quartz stringers cutting the albitite or the adjacent wall rocks or
else are in rusty spots in the albitite dike itself. Photo by Mary H. Rice.
There are three veins on the Whitlock group of claims, the Whitlock,
Alabama and Westward. The Whitlock vein strikes north to N. 10°
E., dips 75° east to nearly vertical, and ranges from 4 to 10 feet wide.
Vein matter is chiefly milky quartz. Ore minerals are chiefly pyrite
and minor chalcopyrite with native gold, but locally argentiferous ga-
lena is prominent — particularly in the ore mined in 1900. From the
stopes described in old accounts there apparently were two main ore-
shoots, one about 150 feet long and one about 240 feet long. Wall rocks
are massive pyroxene andesite greenstone of unknown age. The
Alabama and Westward veins are roughly parallel with the Whitlock
vein but diverge slightly toward it to the north. They are less well de-
fined and apparently contained less ore than the Whitlock vein. In
any event the Westward vein was very superficially developed and
workings on the Alabama vein are much less extensive than those on
the Whitlock vein.
Principal workings on the Whitlock vein are a 900-foot, steeply in-
clined shaft, with 4 levels, and a 600-foot crosscut adit with connecting
drifts. Drifts connecting with the main shaft aggregate about 3000
Nos. 1 and 2] mines and mineral deposits, mariposa county 185
feet (Castello, 1921, p. 142) and those connecting with the crosscut
total several hundred feet. There are several other crosscut adits of
unknown length. None of the workings have been recently used and
must be cleaned out (August, 1954). The Alabama vein has been de-
veloped by an inclined shaft and connecting drifts of unknown extent.
These workings are also inaccessible.
Williams Brothers (Gibbs) Mine. Location: Sees. 31, 32, T. 3 S.,
R. 20 E., M.D., on the southeast slope of Brown Peak 400 feet below
the divide at Canty Meadow. It is 3 miles south and 1 mile west of El
Portal and is accessible by about 9 miles of steep mountain road via
Cold Canyon.
Ownership : Earl, Ray, Fred and G. H. Williams and Ralph Zelers,
address El Portal, California or Rt. 1, Box 1061 E., Modesto, Cali-
fornia, hold four unpatented claims the Williams Brothers and the 2, 4
and 5 extensions, totaling about 80 acres.
The Williams Brothers mine, known in the early days as the Gibbs
mine, was probably first worked in the 1860s about the time of discovery
of the nearby Hite mine and the adjacent Mexican or El Carmen mine.
It was developed by 3 drift adits which are now being rehabilitated.
Driving of these workings was done partly in 1875 (Min. and Sci. Press,
vol. 30, p. 364). Because of its relative inaccessibility little or no work
had been done for several decades until the present owners acquired
the property in the late 1940s. In 1949 a 5-ton Gibson mill was packed
to the mine by horseback for mill testing and some high-grade ore
found on the dump was processed at this time. In 1950 a 9-mile road
into the property from Highway 140 was started by the Williams part-
nership. Pacific Placers Engineers Company entered into a joint con-
tract with the Williams group for construction of the road to the Wil-
liams Brothers and Kaderitas mines. The road was completed to the
Williams Brothers mine in December 1952. A 5-stamp mill was com-
pleted in 1953 and for some time ran on ore taken from old dumps. The
dump material yielded about $10 per ton. In 1954 work was started on
the lowermost of three old adits. Some ore mined that year ran $27.22
per ton in gold. Development was still progressing in September, 1955.
The principal vein on the property strikes about N. 40° W. and dips
northeast at angles varying from 25° to nearly vertical. Vein matter is
chiefly milky to glassy quartz containing wall-rock fragments. Vein
matter is 6 to 20 feet thick averaging perhaps 6 or 8 feet. Gold occurs in
small shoots and pockets in the quartz commonly associated with frac-
tured, friable pyrite. Flecks of other sulfides such as sphalerite, galena
and arsenopyrite may be seen in some of the ore but are not common.
The vein matter characteristically is full of vugs or small cavities lined
with masses of spongy to friable pyrite. The trend of the ore shoots had
not been determined at the time of the author's visit to the mine in
September, 1954.
Workings consist of 3 adits 150, 75 and 200 feet long, respectively,
upper to lower. These were in process of being cleaned out in Sep-
tember, 1954 and some raising and stoping was being done above the
lower adit level. There apparently had been considerable stoping from
the upper levels in early days.
The 5-stamp mill has a capacity of 1 ton per hour. Ore is crushed in
an 8-inch jaw crusher and the 5 stamps to pass a 45-mesh screen. It is

Yellowstone (Yellowstone-Sirocco, Sirocco) Mine. Location : Sec. 19,
T. 4 S., R. 17 E., M.D., just north of the paved Bear Valley-Hornitos
road li miles west of Bear Valley. Ownership : Not determined. Last
operator was Glenn Coburn of Mariposa (1941).
The Yellowstone mine was discovered sometime prior to 1893. During
that year it was operated by Burt and Bach of Bear Valley (Storms,
1894, p. 175) under the name Sirocco mine and had extensive under-
ground workings and steam hoisting equipment. In 1896 the operators
were listed as the Yellowstone Mining Company of San Francisco,
C. H. Burt of Bear Valley acting as superintendent (Storms, 1896,
p. 224). The mine was then called the Yellowstone-Sirocco mine. About
1897 the property was taken over under bond by a Chicago group with
G. Seymour acting as superintendent (Min. and Sci. Press, vol. 74,
no. 8, p. 154, 1897). At that time the main shaft was 420 feet deep and
a second shaft at the west end of the property was down 70 feet. Good
ore was reported to be coming from both shafts (Eng. and Min. Jour.,
vol. 63, no. 10, 240, 1897). About $22,000 in gold was recovered be-
tween 1896 and 1897 (U.S. Bureau of Mines records). The mine ap-
parently lay idle until about 1935 but about 650 tons of low-grade ore
was produced between 1935 and 1941, most of this by Glenn Coburn
of Mariposa (U. S. Bureau of Mines records). There has been no
recent activity at the property except for utilization of the extensive
dumps for road base and fill.
The Yellowstone mine workings are chiefly on a narrow shear zone
striking N. 40-45° E. and dipping 75° northwest. Quartz occurs in pods
and larger lenticular masses in sheared greenstone (pyroxene andesite).
Storms (1896, p. 224) describe calcitic masses in the vein but none of
these were observed at the surface. Gold occurs in quartz and in ad-
jacent schistose wall rock, according to Storms (1896, p. 175). No ore
minerals were found on the dump by the authors.
Workings originally consisted of a 420-foot and a 70-foot inclined
shaft and at least 2 crosscut adits. One of these trended about N. 45° W.
and the other nearly due north. None of the workings are accessible
owing to caving. Judging from the size of the dumps the underground
workings must be extensive. Ore apparently was very pockety.
Placer Mines
Placer deposits in Mariposa County were worked as early as 1848,
and possibly earlier, by Californians of Spanish descent. These opera-
tions apparently began on Agua Fria Creek, rapidly spread to the
Hornitos district and before 1870 had spread to almost every creek
and gulch west of a cross-county line joining Wawona and El Portal.
There are few if any gold-quartz veins east of this line. During the
first two decades mining was carried on almost exclusively by hand
methods. In the late 1860s and during the 1870s some hydraulicking
and ground sluicing were done, notably along the Merced River west
of Bagby and at the Schroeder placer ground west of Sherlock Creek.
Very little drift mining for buried placers has been done in Mariposa
County as such deposits are rare. Some drift mining was carried on

Nos. 1 and 2] mines and mineral deposits, mariposa county 189
at the Weston bench-gravel ground southeast of the Diltz mine on
Sherlock Creek and at the Schroeder property previously mentioned.
Only 3 patches of Tertiary gravels have been found in the county,
one about 4 miles northwest of Forty Nine Gap in the Blanchard dis-
trict of northwestern Mariposa County, a second (the largest) on the
county line south of Jawbone Ridge, Tuolumne County, and the third
high on the ridge lying between Moore and Jordan Creeks 4 to 5 miles
northwest of Bower Cave. These produced considerable gold in early
days but have long since been worked out.
Bench gravels of Quaternary, possibly Pleistocene age, have been
worked on the old Weston property east of Sherlock Creek and south-
east of the Diltz mine and there probably were others of this type in
the county. Unfortunately, these deposits have been so thoroughly dis-
turbed that their original character and distribution cannot be easily
ascertained.
Much of the placering, hydraulicking and ground sluicing done in
the county has been on the weathered, uppermost parts of the quartz
veins themselves or the soil mantle covering them. Deposits of this sort
commonly were very rich in coarse gold and more than a few important
underground mines were financed b}r the easily recovered gold found
near the vein outcrop. Notable amounts of gold were recovered from
such material at the Diltz, Schroeder, and Mt. Gaines mines and at
many of the mines in the Colorado district such as the Landrum, Artru
and Champion.
All of the other placer deposits in the county are Quaternary stream-
bed deposits or shallow bench gravels lying only a few feet above the
present high water levels of the contemporary streams. Although there
is a steady dribble of placer gold coming from small patches of ground
overlooked in the early days or from material reconcentrated during
times of high water by present streams, most of the production during
the last 2 decades has been from dredges processing material too low in
grade to have attracted the early-day placer miner. These only became
profitable to work when heavy equipment was designed to handle huge
yardages at very low cost. Dredges operated within the past 25 years
have, for the most part, processed ground that yielded from 13 to 25
cents per cubic yard. A little ground was worked that ran as low as
7 cents per cubic yard. Most of the recent dredging has been done
along Mariposa, Burns, Eldorado, Cotton and Temperance Creeks.
Julihn and Horton (1940, p. 159) have estimated that the total
placer gold production up to 1870 probably did not exceed $10,000,000.
If this figure is accepted then the total production of placer gold in
Mariposa County to 1955 is about $12,000,000.
Inasmuch as most of the placer ground has been pretty well worked
out and as a majority of the properties are no longer classed as mines,
none are discussed here in detail. Operations within the past 25 years
have been described by Julihn and Horton (1940, pp. 158-162) and
Averill (1946, pp. 261-262). Some data on most of the placer mines
will be found in the accompanying tabulated list.
Lead
Lead has been produced in substantial quantities in Mariposa County
from complex zinc ore and as a by-product in the milling of gold ore.
190 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
The total recorded production of lead up to 1954 has been about 709,508
pounds. The principal producer has been the Blue Moon zinc mine with
a production of 533,753 pounds. Gold mines which have yielded by-
product lead in substantial amounts are the Bondurant (85,000 pounds),
Malvina group (about 25,000 pounds), Pine Tree and Josephine, Mount
Gaines and Washington or Jenny Lind. The complex zinc ores have been
worked almost entirely in wartime. Production of by-product lead fol-
lows fairly closely the production of gold.
The principal primary lead ore-mineral in both the zinc and gold
ores is galena, although minor amounts of lead carbonate and sulfate
probably are present in oxidized parts of the veins. The complex ores
of the Blue Moon mine are confined to shear zones in hydrothermally
altered greenstone, where they form banded deposits parallel to the
schistosity. The greenstone is commonly converted to sericite schist
adjacent to the ore bodies. Some galena is generally present in all types
of gold-bearing veins.
The various lead-producing mines, which number about 20, are dis-
cussed elsewhere under the headings zinc and gold. With the exception
of those listed above, these have produced less that 3000 pounds of
lead each.
Manganese
Manganese has been mined in a small way in Mariposa County dur-
ing wartime periods of high price and government subsidy. Only a few
hundreds of tons of ore have been marketed. Most of the known occur-
rences fall in two districts, the Granite Springs-Jasper Point district
5 airline miles southwest of Coulterville, and the Sweetwater district
2 miles northwest of Jerseydale and 10 miles northeast of Mariposa.
Manganese occurs in sedimentary deposits associated with chert or
metamorphosed sedimentary deposits, chiefly quartzite derived from
chert. Volcanic rocks are commonly associated with the cherts, and the
manganese is generally believed to have originated in mineral water
introduced onto the sea floor by volcanic activity. None of the deposits
are in the form of hydrothermally deposited veins. The manganiferous
cherts southwest of Coulterville are found in a northwest-trending belt
in the Hunter Valley Chert formation of the Upper Jurassic Amador
group (Taliaferro, 1943, p. 283). Associated with the chert, which
occurs in lenticular masses up to several hundred feet thick and 4 miles
long, are tuffaceous sediments and submarine lava flows. Manganiferous
parts of the chert masses generally are only a few feet wide and less
than a hundred feet long, although a manganiferous zone over 750
feet long has been found at the Caldwell mine. In the Sweetwater dis-
trict manganese ore occurs in small lenticular and irregular masses
within quartzite. The quartzite is a laminated rock derived from chert
and is associated with schist and phyllite derived from shale. These
rocks belong to the Paleozoic Calaveras group and occur in the Jersey-
dale district principally as pendants in granitic rocks.
Most of the manganese occurrences have been explored very super-
ficially and no large reserves have been proved thus far. All of the
known deposits in California were studied in considerable detail by
Federal agencies during the wartime periods of World Wars I and II.
The results of these studies have been published as Bulletins 125 and
Nos. 1 and 2] mines and mineral deposits, mariposa county 191
152 of the State Division of Mines. The following mine description and
the tabulated list data have been abstracted from pages 106-112 of
Bulletin 152 written by Ivan F. Wilson and N. L. Taliaferro. The
deposits have been inactive for more than 10 years and were not visited
by the authors during this investigation.
Caldwell (Daly) Mine. Location: NEi sec. 14, T. 4 S., R. 15 E.,
M. D., on the Caldwell Ranch 1.5 miles south of Granite Springs School
and 7 miles west of Coulterville via State Highway 132. Ownership:
The mine is on patented agricultural land, ownership of which was not
determined.
The Caldwell mine is the most extensively developed manganese prop-
erty in the county and the only one having recorded production. First
worked during World War I as the Daly mine, it produced between
100 and 200 tons of ore. About 1937 the mine was reactivated and pro-
duced some ore between 1937 and 1943. The total production has been
about 265 tons of ore averaging nearly 45 percent manganese.
The principal (north) group of workings lies along a single bed or
connected series of lenses 2 to 5 feet thick enclosed in chert of the
Upper Jurassic Hunter Valley formation. The ore is associated with
thick-bedded red chert, thin-bedded buff-to-gray chert and thick-bedded
white chert. These cherts are enclosed in gray and green metatuff and
andesite greenstone. The manganiferous zone is traceable for more than
1000 feet in the northern group of workings. Ore minerals are chiefly
black psilomelane and pyrolusite but there is considerable carbonate
ore consisting of brown, gray and pink manganocalcite. Manganocalcite
ore runs 20-30 percent manganese, which in past years has been too
low grade to mine. Over much of its length the ore zone strikes N. 5° E.
and dips 50-80° east, but is markedly sinuous over part of its length
and the dips locally change to steeply west.
There is an inclined shaft 57 feet deep along a 45° incline with a
26-foot drift at the bottom. A second shaft 10 feet deep is 500 feet
south of the main shaft and a third shaft 15 feet deep lies 800 feet south
of the main shaft. There are also about 30 open cuts scattered along the
ore-zone for a distance of more than 1000 feet.
A quarter of a mile south of the principal or northern group of
workings and apparently on the same chert belt is a second group of
shallow workings covering a distance of 170 feet. There the chert is
thin-bedded and has thin interlaminations of shale. These beds strike
N. 45° W. and dip 55° N.E. A few inches to 2 feet of soft, shaly, black
oxide ore is exposed at the southern end of the ore-zone and the dump
contained about 13 tons of ore in 1942.
The 1918 production of the mine (about 100 tons) averaged 45 per-
cent manganese, 6 percent iron and 13 percent silica. Nine tons of ore
shipped in 1942 ran 49.3 percent manganese, 4.1 percent aluminum,
2.1 percent iron, 0.038 percent phosphorus and 11.3 percent silica. Ore
running at least 20 percent manganese remained in the mine in 1942.
Nickel
Nickel occurs in Mariposa County in minor amounts in Mother Lode
gold-quartz veins, notably at the Pine Tree and Josephine mine just
south of Bagby. It is found in the primary minerals niccolite (nickel
arsenide) and millerite (nickel sulfide) associated with pyrite, arseno-
192 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
pyrite, chalcopyrite, sphalerite, galena and native gold. The nickel con-
tent of the sulfide concentrates from the Pine Tree and Josephine mine
ranged from 0.35 to 1.35 percent ; during 1936 the concentrates aver-
aged 0.77 percent (Julihn and Horton, 1940, p. 110). No attempt has
been made thus far to recover the nickel.
Nickel is also found in trace amounts (0.2-0.8%) in almost all of the
serpentines of the foothill gold belt and may possibly be found within
the county concentrated in small garnierite-rich lateritic deposits on
ancient, deeply weathered surfaces worn on serpentine.
Platinum
Finds of platinum have been reported in Mariposa County from time
to time; the Platinum King group in sec. 31, T. 3 S., R. 17 E., and the
Clark or Devils Gulch claims in sees. 1 and 12, T. 4 S., R. 19 E., M.D.
have allegedly contained the greatest amount. No platinum has been
marketed from any of these vein deposits and its presence has never
been authenticated. On the Devils Gulch claim platinum was reported
to occur in 2 zones each a few inches wide on both sides of barren
quartz vein matter associated with gold and with minor cobalt, nickel
and tin. Such an association is improbable and it is possible that the
metals were misidentified.
Platinum-group metals occur in minor amounts in placer gold de-
posits of the county but so far the authors have been able to determine
only an ounce or two has been recovered — from dredge ground in the
Hornitos district.
Quicksilver
Cinnabar in small quantities has been found in the Crystal mine on
the southwest slope of Horseshoe Bend Mountain in sees. 15, 16, T. 3 S.
R. 16 E., M.D. Two specimens of high-grade ore from this locality are
on display in the Division of Mines museum in the Ferry Building,
San Francisco. The vertical Crystal vein worked principally for gold,
strikes N. 60° E., intersecting the Cabinet and Lookout veins at right
angles. Cinnabar occurs as drusy crystal groups and blebs in calcite
vein-matter and in hydrothermally altered greenstone close to the vein.
The quantity of ore uncovered apparently was very small and no quick-
silver was ever recovered from the cinnabar ore.
Silver
Mesothermal quartz veins carrying native gold and silver and the
silver sulfo-salts proustite and pyrargyrite are found in the Bootjack
district of southern Mariposa County, notably at the Silver Bar and
Silver Lane mines. This type of occurrence is unique among the mines
of the county, most of the silver having been recovered from ores con-
taining gold-silver alloys or from argentiferous galena in gold mines.
The total silver recovered from this type of deposit has been small,
however, and the very substantial silver production of Mariposa
County, amounting to about $345,000, has come principally from mines
worked primarily for gold.

The Silver Bar mine known also as the Bryan or Silver mine, was
worked in a small way prior to 1927. A small production was recorded
for the years 1909, 1920 and 1921. During- 1927 the property was oper-
ated under lease by A. D. Lane, et al., of Mariposa. This management
did considerable development work and built a small mill, and a small
production was realized in 1930. During the late 1930 's the mine was
operated by Richard E. Jeffery of Mariposa. Most of the silver produc-
tion was made in 1930. In other years gold has been the principal metal
recovered, from the point of view of value.
The Silver Bar vein strikes N. 60-65° W., dips 45° southwest and
ranges from a few inches up to 5 feet wide. Near the surface the width
seldom exceeds 1 foot. Ore exposed on the dump showed galena, pyrite,
arsenopyrite and argentite. Proustite, pyrargyrite, native silver and
gold are also reported in the ore from the mine (Julihn and Horton,
1940, p. 163). Wall rocks are hornblende biotite granodiorite or quartz
diorite of Upper Jurassic or early Cretaceous age. In 1939 ore was said
to average 15 to 20 oz. of silver and 0.15 oz. of gold per ton (Julihn
and Horton, 1940, p. 163). The tonnage of ore mined or blocked out
at that time was about 4000 tons.

Workings (September, 1954) consist of a 257-foot shaft, inclined 45°
southwest, surmounted by an ore bin and crusher housing, and a partly
caved drift adit striking N. 65-70° W. The headframe of the shaft has
been demolished and the shaft is partly caved and inaccessible. The

levels at 100 and 200 feet, the 100-level having a 235-foot east drift
and an 85-foot west drift, and the 200-level having a 263-foot east drift
and a 245-foot west drift.
Milling equipment includes a 5-foot Huntington mill, small tube mill,
two small ball mills, a Union compressor, and two Kraut flotation cells.
One small cabin is the only building on the property. The mine makes
about 750 gallons of water a day and water shortage has limited past
operations.

The early history of the Silver Lane mine has not been recorded
although much of the area has been ground-sluiced and presumably
started as a placer area. The principal period of operation was 1933
to 1938 by the Silver Lane Gold Mining Company, A. D. Lane, et al.,

ined roasting and chlorination, included a 50-ton crusher, rod mill,
oasting furnace and leaching tank (Laizure, 1935, pp. 44-45). The
oist and compressor were steam-powered as steam was to be utilized in
he extraction process. Ore reserves believed to contain $60,000 were
eveloped but only a small part of the ore was ever processed. The op-
ration was greatly hampered by insufficient water. All equipment in-
luding the headframe, ore bin and buildings has been removed and the
iroperty was idle in September, 1954.
At the surface a quartz vein 8 inches to 14 inches wide strikes N.
0° W. and dips 35-45° southwest. The vein is reported to average
feet wide at depth (Laizure, 1935, p. 44) and to contain the ore
ninerals argentite, proustite, pyrargyrite, cerargyrite, native silver,
yrite, galena and a little gold (Julihn and Horton, 1940, p. 164).
)re remaining on the dump in 1954 contained pyrite, chalcopyrite,
yrargyrite, galena and argentite ( ?). Gangue material is chiefly milky
nd glassy quartz with vugs and crude comb structures. Wall rocks
ire hornblende biotite granodiorite or quartz diorite. Several tons of
>re shipped to Selby smelter in 1938 yielded $38.50 in silver and $5.50
n gold (Julihn and Horton, 1940, p. 164).
Workings consist of a 240-foot inclined shaft with 2 levels and a
econd shaft of unknown extent. There is a 90-foot east drift on the
00-level and a 72-foot east and 21-foot west drift on the 200-level.
Both shafts were caved and inaccessible in September 1954.
Tungsten
Tungsten occurs in Mariposa County in mesothermal gold-bearing
veins and as replacement disseminations in metamorphic rocks adjacent
;o granitic intrusive contacts. In both of these types of occurrences the
Drincipal ore mineral is scheelite, calcium tungstate. Wolframite (iron-
nanganese tungstate) has been found in small amounts in quartz near
;he Buchanan mine 6 miles southwest of Raymond, Madera County,
md might be expected in adjacent southwestern Mariposa County, also.
Contact metamorphic rocks (tactites and skarn rocks) containing
scheelite most readily develop at the borders of limestone and dolomite
pendants but are also found in aluminous rocks such as mica schists
ind spotted slates. At the Big Grizzly group of claims in Ned Gulch
1^ miles northwest of Clearinghouse scheelite occurs in gold-bearing
quartz veins (Tucker and Sampson, 1941, p. 580). Scheelite also is
known to occur disseminated in quartz veins at the Early mine in the
Sweetwater district 2 airline miles northwest of Jerseydale.
Most of the recent activity in tungsten has centered around El Portal
where the Incline Mining Company of San Francisco has been develop-
ing several groups of tungsten claims. A new tungsten-ore-processing
mill was built by the company and placed in operation by John P.
Jones. It is close to the north bank of the Merced River half a mile
by road west of the El Portal barite-processing plant on Rancheria
Plat. Storms, which washed out roads to the tungsten mines, caused
a temporary shutdown of the mill in February, 1956. Future activity
in tungsten in Mariposa County will depend largely upon the con-
tinuation of the government stockpiling program and upon the tung-
sten price supports as there are no known high-grade deposits.

L. Garribotti, et al., of San Francisco.
The Blue Dipper mine is a recent discovery on which there has been
considerable capital outlay in road building and other development
work. Some ore was produced and milled at the Incline Mining Com-
pany mill on the Merced River during 1955 before the November-
December floods washed out the road to the mine. Operations were
scheduled to continue later in the spring of 1956.
Scheelite occurs in tactite in a small pendant of limestone cropping
out over an acre or two of very steep terrain. The general strike of the
tactite bearing limestone is N. 30° W. and the dip is 70° northeast.
The limestone pendant is bordered on the east by horblende granodi-
orite or quartz diorite. The tactite is crudely banded through increase
in the garnet and epidote content. The chief mineral in the tactite is
quartz with subordinate calcite, garnet, epidote, pyrrhotite, scheelite,
tremolite and wollastonite. Some scheelite occurs in the granodiorite
which has intruded the pendant in small patches and to some extent in
the bordering granitic massif. The ore averages about 0.75 percent

tungsten. In August 1954 the principal workings were an upper tunnel,
with several galleries, striking N. 55° E. and about 100 feet long.
Scheelite ore was almost continuously exposed in this tunnel. A second
tunnel has been driven southeast about 65 feet below the main tunnel.
This was about 50 feet long in August 1954.
Zinc
Complex ores containing substantial amounts of zinc, copper, and
lead and minor amounts of gold and silver have been found in Mariposa
County in a narrow, northwest-trending belt astride the Merced River
between Hornitos and Webb Station. The principal mines in this belt
are the Blue Moon and the American Eagle. Nearly all of the zinc
production for Mariposa County was made during the World War II
years, notably 1944 and 1945, when the Blue Moon mine produced
14,687,920 pounds (Eric and Cox, 1948, p. 145).
Minor amounts of zinc are present in most gold ores of the county
but not in quantities sufficiently large to attempt recovery. Zinc is an
undesirable constituent in gold ores and concentrates that are to be
smelted, and if present in more than trace amounts many commercial
smelters assess a penalty on shippers proportional to the amount of zinc
present. Consequently, zinc is seldom recovered as a by-product of gold
mining.
The principal zinc-bearing mineral is the sulfide sphalerite, both in
the complex zinc-copper-lead ores and in the gold-quartz veins. In the
198 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
zinc belt ore commonly occurs in steeply dipping tabular masses in
shear zones in hydrothermally altered greenstone. In the gold-quartz
veins sphalerite generally is sparsely disseminated through the ore
shoots along with other sulfides such as pyrite, galena, tetrahedrite,
arsenopyrite and galena.
Akoz (B.A.B., Radium, Asposozien) Mine. Location : Sees. 9, 10,
T. 4 S., R. 15 E., M.D., near Webb Station on the Merced Falls-Granite
Springs road and 5J airline miles north of Merced Falls. Accessible by
three quarters of a mile of dirt road from Webb Station. It is 7.8 miles
from Merced Falls. Ownership: Carlin Estate, c/o Mrs. P. Erickson,
La Grange, California.
The Akoz mine apparently was prospected prior to 1900 and may
have produced a little gold-silver ore from the surface oxidized zone,
but there is no early record of production. In the early 1900 's the un-
usual triboluminescence of the sphalerite was mistaken for the glow
given off by radium, and a small quantity of ore was mined, pulverized
and marketed for medicinal purposes by the Asposozien Company. At
that time the mine was variously known as the Radium, Akoz and
Asposozien, Akoz being the trade name of the pharmaceutical product.
A 90-foot shaft was sunk during this operation.
About 1941 the mine was leased by a partnership of L. M. Brady,
E. M. Aldrich and Menard Brihten (Wiebelt, 1947, p. 3) and the mine
was renamed the B.A.B. Under this management considerable stripping
was done and the shaft was reopened to the 60-level. In 1944 about 81
tons of ore was shipped that yielded 1.41 oz. of gold, 52 oz. of silver,
1068 pounds of lead and 3623 pounds of copper. Zinc was not recovered
from any of this ore and there was no attempt to recover lead or copper
from part of it. The yield was between $5 and $6 per ton (Wiebelt,
1947, p. 3).
Further development work was done between 1944 and 1946, the
latest by F. H. A. Williams of New York. This culminated in the sam-
pling and diamond-drilling of the deposit by the U. S. Bureau of Mines
in 1946. Mining was discontinued in 1947 and no further work has
been done.
The following discussion is derived chiefly from the U. S. Bureau of
Mines Report of Investigations No. 4144 by Frank J. Wiebelt, with
minor additions and corrections by the authors.
Ore occurs in irregular replacement masses in micaceous schist de-
rived from greenstone and cut by greenstone dikes. The mineralized
zone is roughly 400 by 800 feet in plan and is elongated roughly north-
west. Among the primary sulfide minerals sphalerite predominates;
other species include pyrite, chalcopyrito and argentiferous galena.
Barite and quartz are the common gangue minerals, quartz being pre-
sent most conspicuously as stringers and pods. The ore has been oxi-
dized almost completely to a depth of 35 feet and partly oridized 15
feet deeper. The best precious-metal ore has come from the oxidized
zone but the best zinc-ore lies below the oxidized zone. A sample taken
by the U. S. Bureau of Mines across a width of 3 feet of massive sulfide
ore at a depth of 55 feet in the main shaft tested 0.12 oz. of gold and
10.9 oz. of silver per ton and 12.83 percent zinc, 0.79 percent lead and
0.87 percent copper. None of the other samples taken underground
iNos. 1 and 2] mines and mineral deposits, mariposa county 199
contained over 3.5 percent zinc and 3.2 oz. of silver per ton and none
of the surface samples contained over 3.5 percent zinc. The principal
lvalues in the near surface samples were in silver and gold, several of
the samples being in the range of 9 to 21 oz. of silver per ton. Complete
sampling and diamond drill data are listed by Wiebelt (pp. 4-6).
The principal working at the Akoz mine is a 90-foot shaft from
which short drifts were run from the 35, 60 and 90-foot levels. This
is on the main ore zone which is also developed by numerous surface
cuts. About 800 feet east of the main shaft is a second shaft 15 feet
deep. Promising ore apparently was not found there as there are few
additional workings.
American Eagle (Bullion Hill, Blue Bell and Bonanza) Mine. Loca-
tion : N. i Sec. 30, T. 4 S., R. 16 E., M.D., 3 miles by road northwest
of Hornitos. Adjoins the Blue Moon mine on the south. Ownership:

Box 568, Portola, California.
The American Eagle mine is an old property worked in the 1890s
and early 1900s for gold and silver. A substantial amount of gold was
produced in 1899 and the 300-foot-long American Eagle adit was
driven. Owners in 1910 were listed as L. Valberde and John Morrison
and the mine was being operated by the Bullion Hill Mining Company.
(Min. and Sci. Press, vol. 90, 91, several entries). Considerable ore
was shipped. In 1911 the mine was sold to J. M. and A. L. Richardson
of Minneapolis and a Huntington mill was installed. The mine fell
idle about 1912 and little was done with it until about 1942 when
F. H. A. Williams of New York did some development work and
shipped some ore (Eric and Co., 1948, p. 143). The property has been
inactive since 1942.
The American Eagle and Blue Moon mines were intensively explored
and studied by the U. S. Bureau of Mines and the U. S. Geological
Survey during World War II. The following discussion is abstracted
largely from the report on the American Eagle and Blue Moon mines
by U. S. Geological Survey geologists J. H. Eric and M. W. Cox pub-
lished in California State Division of Mines Bulletin 144 (1948, pp.
133-150).
There are six overlapping, en echelon mineralized zones on the
American Eagle property strung out in northwesterly direction over a
length of over 1000 feet. Only one, zone A, the most westerly, pene-
trated by the main crosscut adit, gives promise of bearing ore of eco-
nomic grade and quantity. This has been explored for a strike length
of about 200 feet and varies from a few inches to 4 feet wide. Sixteen
channel samples cut from the bottom and sides of a 40-foot winze,
sunk on zone A from the adit level at a point about 60 feet north of
the crosscut yielded assays within the following ranges:
copper 1.53 to 11.01 percent
zinc 2.59 to 8.29 percent
lead O.Tito 1.02 percent
gold 0.01 to 0.22 oz. per ton
silver 0.99 to 2.58 oz. per ton
The ore body where the samples were taken is about 4 feet wide and
consists of partly oxidized sulfides. Ore minerals include sphalerite,
200 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
pyrite, tetrahedrite, galena and chalcopyrite. Gangue minerals are
barite, glossy and milky quartz, sericite and calcite. Above the adit
level the ore is largely oxidized showing streaks of azurite and ma-
lachite. Most of the high-grade gold-silver ore taken out in early days
came from near-surface, oxidized ground.
Ore bodies tend to be tabular and are elongated parallel to the schis-
tosity of the enclosing schist. The principal mineralized zone is found
in sheared felsite breccia or tuff near its contact with massive felsitic
volcanic rock. These metavolcanics are cut by greenstone dikes. The
ore-enclosing schist has formed by shearing and hydrothermal altera-
tion of the metavolcanic rocks.
Most of the workings of the American Eagle mine connect with the
main crosscut adit-level which penetrates about 120 feet below the top
of the ridge. This adit is somewhat sinuous and is driven slightly north
of east for about 300 feet, intersecting both ore zone A and a secondary
zone (named B). From the adit level is a 100-foot southeast drift
driven on ore zone B and a 200-foot sinuous drift driven slightly west
of north from the crosscut, largely on ore zone A. About 60 feet north
of the crosscut adit is the winze previously mentioned and just north
of the winze is a 100-foot raise to the surface. South of the winze is a
short stope about 25 feet high. The surface croppings of the various
mineralized zones have also been explored by about 50 shallow trenches,
pits and shafts.
Although zinc and copper are the principal constituents of the com-
plex ores at the American Eagle mine, the principal production, in
regard to value, has been in gold and silver. A satisfactory total pro-
duction figure is not available for this mine.
Blue Moon (Blue Cloud, Red Cloud, Porcupine) Mine. Location:
Sees. 19, 30, T. 4 S., R. 16 E., M.D., 4 airline miles northwest of
Hornitos. Accessible by 5 miles of dirt road from the paved Hornitos-
Bear Valley road, the turnoff being 1.2 miles north of the Merced Falls-
Hornitos-Mt. Bullion road. Ownership : Not determined. Last operator
(1945) was Hecla Mining Company of Wallace, Idaho. The property
includes the Porcupine, Porcupine Fraction and Blue Moon group of
claims.
Although the Blue Moon deposits were probably discovered and
superficially worked for gold and silver at various times during the
last half of the nineteenth eentun^ all but a minor fraction of the pro-
duction was made between 1943 and 1946 under the impetus of the
wartime demand for base-metals. A little gold, silver and copper pro-
duction was recorded during the middle 1930s from near-surface
oxidized ore (U.S. Bureau of Mines records). From 1940 to 1943 the
Red Cloud Mines, Inc. explored the mineralized zones by shallow under-
ground workings and by diamond drill-holes aggregating 5000 feet.
Two zones containing promising deposits were outlined as well as an
additional silicified ore zone bordering the west ore zone on the north.
In 1943 the property was taken under active exploitation by Hecla
Mining Company of Wallace, Idaho. The mine was equipped to handle
200 tons of ore daily and flotation concentrate was made at the mill of
the Washington mine, 4 miles distant to the southeast. Mining ceased in
November 1945 because of caving in the mine and because of the un-
certainty of postwar conditions. The property has been idle since 1945.
Nos. 1 and 2] mines and mineral deposits, mariposa county 201
The total production of the Blue Moon mine has been in excess of
$2,054,000, nearly all of the total having been between 1943 and 1946.
During this period the 55,656 tons of complex ore mined yielded nearly
$37.00 per ton — $4.78 per ton in precious metals and $32.07 per ton
in base metals, predominantly zinc. Consequently the Blue Moon mine
ranks among- the 11 highest producing mines in the country and is by
far the highest producing base-metal mine in the county.
The following discussion on the geology and workings of the Blue
Moon mine is drawn largely from Eric arid Cox (1948, pp. 145-148).
The property was studied in detail as part of the wartime investigation
of the foothill copper-zinc belt by the U. S. Geological Survey.
Ore occurs in 3 outcropping, tabular, mineralized zones in altered
sericite schist derived from sheared, fragmental, andesitic volcanic
rocks by hydrothermal alteration. The No. 1 ore body is a lenticular
mass striking north to N. 15° E. and dipping west at angles varying
between 48° and 87°. It is an irregular, lenticular mass reaching a
maximum width of 38 feet and a strike length of 180 feet, and has been
worked to a depth of 450 feet. The No. 2 ore body, separated from the
No. 1 mass by 10 to 20 feet of sheared tuff-breccia roughly parallels
the main body. It has an average width of 5 feet and a strike length
of about 80 feet at the 165-foot level, but is believed to pinch out both
above and below the 165-level. It apparently converges and joins the
No. 1 ore body at its south end. This ore body has not been exploited.
A third mineralized zone in the vicinity of the Number 2 shaft is be-
lieved to be a southern extension of the main ore zone. About 40 feet
of unmineralized material separates the No. 1 and No. 3 ore bodies.
Its stope length varies from 50 to 80 feet and its width from 4 to 9
feet. Ore extends well below the 165-foot level but has not been ex-
ploited beyond that depth. The ore body strikes N. 5° E. and dips about
80° west.
About 160 feet west of the No. 1 shaft is a silicified zone not mineral-
ized at the surface but containing sulfide ore at depth as demonstrated
by several diamond drill holes. This zone has not been exploited but is
believed to contain several lenticular, south-plunging ore bodies carry-
ing 6 to 10 percent zinc and having a higher lead content than the main
ore zone. Detailed data concerning the geology, and disposition of ore
bodies and workings of both the main and west ore zones are contained
in the paper by Eric and Cox, previously cited.
The mineralized zones are found in metavolcanic rocks of the Penon
Blanco formation of the Upper Jurassic Amador group (Taliaferro,
1943, pp. 283-284). This belt of rocks trends about N. 10-20° W. and
dips steeply east. Felsitic greenstone and greenstone tuff-breccia are
the principal rock types in which mineralization took place and shear
zones controlled the influx of mineralizing solutions.
The principal working at the Blue Moon mine is a 500-foot shaft, the
No. 2 inclined 80° W. with levels at 125, 165, 275, 385 and 450 feet.
There are about 200 feet of drifts and subsidiary workings on the
125-level, 600 feet on the 165-level, 250 feet on the 275-level, 225 feet
on the 385-level and 150 feet on the 450-level. Two hundred and fifty
feet south and slightly east of the main or No. 2 shaft is the No. 1
shaft originaly 35 feet deep but later connected to the 165-level of
the main working by a raise. In addition to these underground work-
202 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
ings there are several open cuts, 2 over 100 feet long. The main shaft
and adjoining workings are not accessible because of caving.
Primary ore generally consists of sphalerite and pyrite with minor
amounts of tetrahedrite, galena and chalcopyrite in a gangue of sericite,
barite, clear quartz and calcite. This ore is massive in some places and
banded in others, banding being due to sphalerite-rich layers and
elongated sphalerite grains. Massive siliceous pyritic rock is found along
the foot-wall of the northern ore zone and ore locally consists of mas-
sive sphalerite-barite rock. Ore in the main or No. 1 ore body averaged
13.1 percent zinc, 0.36 percent copper, 0.47 percent lead and 0.061 oz.
of gold and 3.75 oz. of silver per ton.
Non-Metallic Minerals
Andalusite
Andalusite, an aluminum silicate mineral commonly used in the man-
ufacture of electrical porcelain insulators, occurs rather abundantly
in western Mariposa County in black slate, phyllite and schist which
have undergone contact metamorphism. Andalusite-bearing slates and
schists most commonly are found within a few hundred yards of gran-
itic intrusions but occasionally occupy still larger zones adjacent to
large intrusions. In many of the occurrences the andalusite is in the
form of the variety chiastolite, which contains some organic matter and
is commonly altered in some degree to pinnite, a hydro-mica. Chiastolite
and pinnitized chiastolite have little economic value, but unaltered
andalusite, when present in high concentrations near to transportation,
has potential economic importance. The authors have examined one such
occurrence described below, and there undoubtedly are others along the
foothill belt, particularly in Indian Gulch and Raynor Creek quad-
rangles.

miles southwest of Tres Cerritos or Three Buttes. Accessible from
Indian Gulch by 4| miles of unimproved dirt road or from Highway
140 via the old Merced Falls dirt road, a distance of 6^ miles.
Ownership : not determined, probably Ed. P. Waltz, Reno, Nevada.
On patented agricultural land.
The Southwest of Three Buttes deposit is undeveloped. Andalusite
occurs in colorless-to-pink, glassy crystals averaging 3x6 mm in section
and 20 mm long. Only a small percentage of the crystals contain or-
ganic matter and none appear to be pinnitized. Andalusite-bearing slate
crops out over an area of at least 1 acre on rolling terrain, the concen-
tration of andalusite in the slate varying from 15 to 25 percent.
Asbestos
There are numerous occurrences of both cross-fibered chrysotile as-
bestos and slip-fibered tremolite asbestos in the serpentine masses of
Mariposa County. Thus far no concentrations of economic importance
have been found. Serpentines along Highway 49 between Bagby and
Coulterville contain veinlets of cross-fibered chrysotile from a fraction
of a millimeter to 3 mm wide but the chrysotile does not make up more
than a few percent of the rock. It is possible that a systematic search

Barite
Large deposits of barite have been found in the El Portal district in
the Pigeon Gulch-Rancheria Flat vicinity, astride State Highway 140,
and on a ridge lying between Devils Gulch and Granite Creek 2 miles
northwest of Chowchilla Mountain. The two districts are about 6 air-
line miles apart. In the El Portal district massive, medium-to-fine-
granular barite occurs in vein-like masses in metasediments .of the
Calaveras group. Associated rocks are quartzite, limestone, slate,
phyllite and schist. In the vicinity of Chowchilla Mountain barite
also occurs in the Calaveras group of rocks in massive quartzite and
micaceous quartzite without apparent association with limestone.
Barite also occurs in large quantities as a gangue mineral in the
zinc-lead-copper ores of the Blue Moon and American Eagle mines
northwest of Hornitos. Thus far no attempt has been made to recover
barite from these ores.
Almost all of the barite production of Mariposa County has come
from El Portal mine, most of this production being between the years
1910 and 1948. Within this period 398,613 tons of barite was marketed,
valued at $2,760,493. This amounts to about 73 percent of the total
California production of barite and compares favorably with the pro-
duction of many of the best gold mines. Mariposa County remains one
of the largest potential producers of barite in California, but present
market requirements are such that ore must be either very selectively
mined or else ordinary mine-run material must be beneficiated (up-
graded). Mines in Nevada currently supply most of California's barite
requirements.
Egenhoff (Devils Gulch) Deposit. Location: Sees. 17, 21, T. 4 S.,
R. 20 E., M.D., near the top of the main ridge that lies between Granite
Creek Canyon and Devils Gulch, 2 miles northwest of Chowchilla Moun-
tain and 4| airline miles east of Jerseydale. Accessible by 1% miles of
trail from the end of the U. S. Forest Service road on Chowchilla
Mountain. Ownership : California Barite Corporation, c/o Edwin Earl,
1102 Rowan Building, Los Angeles 13, California owns a patented prop-
erty of 44 acres which includes the Barium No. 2, Barium No. 3 and
North Barium Fractional claims. The company also holds 3 unpatented
claims, the Barium No. 3, South Fractional and Camp Lode claims.
This deposit was discovered in 1917 by W. D. Egenhoff who did ex-
tensive exploration and development work on the property. Sold to the
California Barite Corporation in 1929, about $50,000 was spent by this
company in further development work (Laizure, 1935, p. 46) during
the early 1930s. The only substantial production recorded from the
mine was in 1937 when about 800 tons was marketed.
The authors are indebted to Charles J. Kundert, formerly barite
specialist for the Division of Mines, for most of the following data.
Mr. Kundert visited the property in October, 1955.
Barite occurs in metasedimentary rocks of the Paleozoic Calaveras
group. The barite-bearing beds are nearly everywhere enclosed in mas-
sive, blue-gray quartzite which strike N. 25° W. and dip 65° northeast.
Sos. 1 and 2] mines and mineral deposits, mariposa county 205
Within a foot of the contact of quartzite with the barite rock the
quartzite is micaceous. The barite rock is white, granular and contains
some silica. Part of the 1937 production was reported to be witherite,
ndicating that the character of the ore at the Egenhoff and El Portal
leposits is similar, but no witherite was observed on the property at the
:ime of Mr. Kunderts' visit in October 1955. The barite rock is foliated
Darallel to the borders of the ore masses, the foliation planes being about
I inches apart and most conspicuous near the contact with the enclosing
nicaceous quartzite. A brown carbonate mineral, probably calcite, oc-
curs along the foliation planes and as blotches throughout the barite
x)ck. No data are available as to the barite content of the ore.
The barite horizon is readily traced for 50 feet southeast of the main
adit portal and for a hundred feet to the northwest. According to Lai-
sure (1928, p. 144) the horizon has been traced for a total distance of
4500 feet. In 1942 the owners reported that 2000 tons of ore remained
on the dumps and that 25,000 tons had been blocked out in the mine.
Workings consist of a drift adit at least 100 feet long, which develops
extensive backs, and numerous surface cuts. The adit is driven N. 25°
W. from a gulch which indents the southwest side of the main N.-NW.
trending ridge. More than 50 feet of backs are developed toward the
rear of the adit.
El Portal Barite Mine. Location: Sees. 18, 19, T. 3 S., R. 20 E.,
M.D., astride Highway 140 and the Merced River 1^ miles west of El
Portal. Ownership : El Portal Mining Company (a subsidiary of Baroid
Division of National Lead Company), c/o R. J. Groves, Trust Depart-
ment, American Trust Company, 464 California St., San Francisco 20,
California, owns a patented property of 81.42 acres which includes the
Barium 1 and 2, North Barium and South Barium claims.
According to Young (1930, p. 7) the North mine of the El Portal
Barite property was discovered and first worked in the 1880s ; the South
mine was discovered later. First production was recorded in 1910 by
the El Portal Mining Company of San Francisco (a different group
than the present owners), which operated the mine intermittently until
about 1914. Barbour Chemical Company of Alameda operated the prop-
erty under lease for a short period in 1914-15 (Lowell, 1916, p. 571),
and the Western Rock Products Company had it for some time in the
early 1920s. In 1927 the mine was acquired by Yosemite Barium Com-
pany of El Portal. This company opened up the series of lenses south
of the Merced River called the South Mine (Laizure, 1928, p. 144). In
1929 or 1930 the National Pigments Company succeeded the El Portal
Mining Company as operators. This company and its subsequent reor-
ganizations, the National Pigments and Chemical Division and Baroid
Division of National Lead Company, operated the mine more or less
continuously until 1948. The property has been idle since 1948 because
more satisfactory ore can be procured from the company's mines in
Nevada at less cost than can be met at the El Portal plant. Loss of rail
facilities when service was discontinued on the Yosemite Valley Rail-
road was the main factor behind discontinuance of operations of the
El Portal mine.
The barite masses occur as apparent replacements in metasediments
of the Paleozoic Calaveras group. In the South Mine some limestone is
found adjacent to the barite-bearing zone and the barite masses have

Figure 54. Mill installation and mine workings at FjI Portal barite mines astride
Highway 140 between Briceburg and El Portal. Barite-witherite rock was mined
chiefly for use in weighting oil-well drilling-mud. Workings of the North mine, shown
at the right of the photo, are in two parallel veins of grayish-white rock which strike
directly away from the observer and dip very steeply toward the right (east). The
lenticular masses of rock range from 3 or 4 feet in width to more than 20 feet in
width and have been mined to a depth of over 200 feet with no lessening of ore at
depth. To keep producing a uniform product having a specific gravity of 4.2 it was
necessary to beneficiate or upgrade the ore by flotation in the mill seen at the left
of the photo. The mines closed down about the time that service was discontinued on
the Yosemite Valley Railroad in 1944. Photo by Mary H. Rice.
long been considered to be replacements of limestone. Whatever the
nature of the parent rock, the barite occurs in apparently homoclinal
sequences of beds associated with quartzite, slate, schist and phyllite.
In the North Mine the main barite-bearing zone ranges from 4 to 20
feet wide, dips 70° west and, although slightly sinuous because of local
thickening and thinning, strikes generally N. 12° E. Within the barite
zone the rock is principally a light-gray to white granular, crystalline
rock. In most places it is about 85-90 percent barite and in other places
barite is mixed with considerable calcite and quartz. Clean, white
barite rock commonly occurs in lenticular masses flanked by several feet
of more impure, sheared material. Contorted structures formed by plas-
tic flow of the barite rock are common within the main ore body. The
barite rock is most commonly a dense, equigranular aggregate of grains
averaging less than half a millimeter in longest dimension. It is com-
monly banded parallel to the walls of the tabular ore bodies, the darker
colored bands containing the most impurities. Impurities include grains
of quartz, pyrite, sphene, tourmaline, magnetite, chlorite, actinolite and
a green pyroxene (Fitch, 1931, p. 462). Witherite locally is abundant
and in places forms distinct ore bodies. In other places calcite takes the
Nos. 1 and 2] mines and mineral deposits, mariposa county 207
place of the normally more abundant barite and the rock approaches a
crystalline limestone in composition and appearances. Ore normally con-
tains about 85 percent barite but was beneficiated to about 94 percent
BaS04 (Julihn and Horton, 1940, p. 169; Young, 1930, p. 71).
A second roughly parallel barite bearing-zone has been developed 75
to 100 feet west of the main zone. This zone, although from 1 to 3 feet
narrower than the main zone, is similar in other respects. South and
east of the North mine across the Merced River is another southeast-
trending group of tabular barite masses which have had considerable
development work done upon them. Wall rocks are slate and metachert
having cleavage and bedding in most places parallel to the planarity of
the barite masses. Locally, however, the barite zone bevels the edges of
the beds. The barite zones are sharply defined between walls of meta-
chert and slate. There are no limestone strata in the vicinity of the
North mine except the calcitic matter found in the barite zones them-
selves. There is a strong suggestion that the barite zones are actually
metamorphosed fissure-vein deposits and not replacements of a pre-
existing bed of limestone. Detailed field and petrographic work would
be necessary to determine whether or not this suggestion is correct.
The main barite zone is developed by a long adit which begins as a
northeast-trending crosscut and then veers north and follows the vein.
The line of overhand and underhand stopes developed from this adit
has almost obliterated the haulageway in some places. The stopes are
open to the surface for long distances and the zone has been mined for
nearly 1000 feet north from the adit entrance. The second productive
zone has been developed by several crosscut adits which connect with
a long line of stopes that are open to the surface. These aggregate about
500 feet of strike length.
Geologic conditions at the South mine are similar to those at the
North mine, although the strike of the ore zone is more to the north-
west. Varying from a width of 6 inches to more than 20 feet the lentic-
ular masses strike N. 45° W., upon the average, and dip 70° northeast
(Kundert, C. J., field report dated in August, 1953). The higher grade
shoots vary in length from 50 to 300 feet. Ore varies from white, uni-
form, medium-grained material to dark-colored, intricately banded rock
having abundant pyrite in very fine particles (Julihn and Horton, 1940,
p. 169). It commonly contains 85 percent barite, 2-3 percent witherite,
0.5 percent pyrite and about 12 percent quartz, but considerable barite
rock falls below 85 percent barite and has not been considered good
enough to process.
The South mine is developed by 2 crosscut adits at the same eleva-
tion and approximately 150 feet apart driven southwest into the west
side of Pigeon Gulch. These connect with a drift level about 1500 feet
long. This level is connected by a 90-foot raise to an upper level about
1000 feet long. Ore has been stoped to the surface for several hundred
feet above the upper level at the northern end of the mine. None of the
workings reach a depth of over 200 feet below the surface (Julihn and
Horton, 1940, p. 169) and ore continues below the adit levels for an
unknown distance. Reserves of high and medium grade ore in both the
North and South mines are believed to be very large.
Good accounts of the processing of the barite ore may be found in
Young (1930, p. 71) and Julihn and Horton (1940, p. 169-170). Most
208 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
of the ore mined was used to add weight to oil well drilling fluids. Ore
was transported from the South Mine to the mill on Rancheria Flat
near the North Mine by aerial tram. The mill and loading facilities
remain intact but have been inactive for several years.
Clay
Clay has not been produced in quantity in Mariposa County thus far,
although a little local material may have been burned into common
brick prior to 1870. Alluvial clay and clay mantle suitable for common
brick and large tile-bodies probably occur at numerous places within
the county boundaries. So far as the authors know there has been no
systematic search for ceramic materials in the county, due mainly to
the distances to market that are involved. Presence of patches of the
Eocene lone formation along the western borders of the county sug-
gest the possibility of the presence of refractory, white clays similar
to those mined in Amador and Placer Counties. White clay of un-
known extent was encountered in a drill-hole in the Huelsdonk
Dredging Company placer ground in sections 5 and 6, T. 4 S., R. 15 E..
M.D., on or adjoining the old Prouty ranch 7 miles northeast of
Merced Falls (L. L. Huelsdonk, personal communication, 1954).
Limestone and Dolomite
There are immense deposits of carbonate rock in Mariposa County
in the Jenkins Hill, Hites Cove, Bower Cave and Exchequer Lake dis-
tricts. Because the deposits are relatively inaccessible or are a long
distance from potential markets, there has been little incentive to
develop any of the deposits in recent years. With the exception of
the deposits on Jenkins Hill, little has been done on the chemical and
physical properties of any of the carbonate rocks in order to determine
their best utilization. In general, the carbonate rocks of the Bull Creek-
Bower Cave district are either magnesian limestones or dolomites;
those of Jenkins Hill tend to be graphitic and slaty (aluminous) ; and
those of the Hite Cove district are at least in part magnesian. Most
of the crystalline limestone on the Hite Cove district is a fine-grained
gray and white marble that takes a good polish. Some of the rock in
the Bower Cove district is similar. The limestone at Jenkins Hill is
nearly black because of the presence of about H percent of finely
divided graphite (Laizure, 1928, p. 148).
Between 1927 and 1944 a total of 2,430,843 tons of limestone was
quarried in Mariposa County, almost entirely from the Emory deposit
on Jenkins Hill. Although this was captive tonnage utilized in manu-
facture of portland cement, it would have been worth between
$2,000,000 and $3,000,000 on the open market. Only a small fraction
of the reserves were utilized.
Bower Cave Deposits. Location: Sees. 19, 20, 29, 30, T. 2 S., R. 18

by road from Briceburg. Ownership : not determined. Portions of the
limestone-bearing land are owned by several individuals.
Lenticular masses of dove-gray carbonate rock crop out along the
east side of the Kinsley-Coulterville road from a point about half a
mile northwest of Bower Cave southeast for a distance of over 3 miles.

These are part of the metasedimentary portion of the Paleozoic Cal-
averas group.
There is some high-calcium limestone in the vicinity of Bower Cave,
the extent of which is not known to the authors, but most of the rock
exposures examined consist mainly of dolomite or a mixture of dolomite
and calcite too intimately mixed to mine separately. Much of the rock
is dense and fine to medium-grained and will take a high polish, but
the colors are not particularly attractive for use as marble in building
facings etc., and the deposits are rather remotely situated from trans-
portation and markets. None of the deposits have been developed or
adequately sampled so far as the authors could find out.
Cotton Creek Deposit. Location: Sec. 18, T. 4 S., R. 16 E., M.D.,
just north of the Cotton Creek arm of Exchequer Lake 3 airline miles
southeast of Granite Springs School. Accessible only by trail from a
ranch road leading southeast from Granite Springs School. The old
road from Hornitos has been inundated by Exchequer Lake. Owner-
ship : not determined.
A small tonnage of limestone was quarried and burned into lime at
the deposit prior to 1910. No recent work has been done. The limestone
occurs in a narrow, northwest-striking lens enveloped in slaty and
schistose marine metasediments of Upper Jurassic age. The limestone
is dense, fine-grained, gray rock apparently high in calcium and low in
magnesium and other impurities. No chemical analytical data are avail-
able on the deposit. The mass is several hundred feet long but does not
exceed a hundred feet wide, and in most places is much thinner than
that. Except for a few small pits the mass is undeveloped.
Jenkins Hill (Emory, Richardson, Timertone, Yosemite Cement) De-
posit. Location: Sees. 7, 18, T. 3 S., R. 19 E., M.D., high on the west
side of Miller Gulch 1 mile north of the Merced River and Highway 140
and 8 miles northeast of Briceburg. Ownership : Johnny Richardson,
1124 South Fifth Avenue, Arcadia, California owns several claims
covering most of the limestone-bearing land.
The Jenkins Hill deposit was put into production in 1927 when the
first rock was shipped to Merced for use in manufacture of portland
cement. Between 1927 and 1944 approximately 2,430,843 tons of lime-
stone was quarried. Production ceased in 1944 when service on the
Yosemite Valley Railroad was discontinued. Limestone was quarried
from long benches situated about 800 feet above the railroad grade, put
through a 30-inch gyratory crusher and a heavy-duty hammer mill,
delivered to the upper storage bin by belt conveyor, and transferred to
the railroad-side storage bin by electrically driven, cable-drawn incline
cars. Each car carried 20 tons of minus-one-inch rock and could travel
at a rate of 500 feet per minute. All equipment and supplies were de-
livered to the quarry area by the inclined cableway track which was
nearly 2000 feet long. The limestone was broken by massive blasts which
brought down as much as a million tons of rock.
Limestone is found in a north-trending lenticular mass nearly half
a mile long and several hundred feet wide at the thickest part of the
lens. The strata dip about 80° east. The mass crosses Miller Gulch and
continues south as far as the Merced River, but it has narrowed to less
than 50 feet wide at that point and is quite slaty. The limestone is ex-

posed by erosion for a depth of more than 800 feet and continues below
the bottom of Miller Gulch for an unknown depth. The limestone is
dark-gray to black and rather thinly bedded. The magnesium oxide
content averages considerably less than 3 percent. Little else regarding
its chemistry has been recorded, but some of the rock is slaty and there-
fore aluminous. In the manufacture of cement the limestone was
blended with alluvium taken from pits near Merced. Only a small per-
centage of the reserves were depleted but the deposit is a mile north of
Highway 140 on rugged terrain and nearly 60 miles to the nearest
rail-shipping point at Planada.
Kinsley (Jenkins Ranch) Deposit. Location : Sees. 4, 9, T. 3 S., R.
18 E., M.D., on the Jenkins ranch half a mile west and slightly south of
the Kinsley guard station of the U. S. Forest Service and about 11
miles by graded dirt road from Briceburg. Ownership : on patented
agricultural land, mostly part of the Jenkins ranch near Kinsley.
Light gray to grayish white limestone crops out over several acres
about half a mile southwest of the Jenkins ranch house. The rock is a
fine-grained dolomitic marble but no chemical or physical data on it
are available. The deposits are undeveloped and the reserves are un-
known. Distance from market, lack of heavy-duty transportation fa-
cilities and the magnesian character of the rock have hindered develop-
ment of the deposit.

River 1| miles south and slightly east of Hite Cove. Accessible by 7
miles of jeep trail from Jerseydale.
The Marble Point deposit is a large, undeveloped mass of finely
crystalline carbonate rock much of which is reported to be good quality
commercial marble. The type rock is white with dark veining and is
dolomitic. The carbonate mass reaches a width of 3000 feet, is more
than half a mile long and has been eroded to a depth of 600 feet. It is
slightly elongated north and dips very steeply east. Little or no work
has been done on the deposit to determine its physical and chemical
properties and it has remained undeveloped because of its inaccessi-
bility.
O'Brien Deposit. Location: N£, NEJ, sec. 11, T. 4 S., R. 18 E.,
M.D., near the crest of a ridge about 1 mile southeast of Briceburg.
Accessible by 5 miles of graded dirt road, via Trabucco Creek and the
Feliciana mine, and 2 miles of truck trail. Ownership : Mrs. Ethel R.
O'Brien, et al., 1534 Clay St., San Francisco owns a patented property
of 80 acres which includes much of the limestone land.
A northwest-striking, nearly vertical lens of limestone several hun-
dred feet thick can be seen cutting across the ridge east of the Brice-
burg grade. There has been no production and reserves have not been
proven beyond the estimate of several million tons (Logan, 1947, p.
253). The best quarry sites are about 800 feet above the bend of the
Merced River. Although the property is 7 miles by road from Highway
140 near Timber Lodge, it would be possible to drop the limestone down
to highway level at Briceburg over a distance of only 1 mile — at the
expense of losing 800 feet of altitude. Three samples analyzed by Santa
Cruz Portland Cement Company (Logan, 1947, p. 253) gave the follow-
ing results :
Sample 1 Sample 2 Sample 3
Oxide (ichite) (black) (mottled)
SiOo 0.28 1.18 0.20
R203 (R = Al&Fe) 0.60 1.02 0.36

MgO not done not done not done
CaCOs 96.54 95.29 97.44
Ign. loss 44.22 43.92 44.48
Logan does not state how the sampling was done or from what parts
of the deposit the samples were taken, but two-thirds of the deposit
contains rock resembling sample No. 3.
Miscellaneous Occurrences. There is a small mass of limestone close
to the north side of Highway 49 one mile northeast of Mt. Bullion, but
it is not sufficiently large or of sufficient purity to be of economic im-
portance. Another deposit, reported to be 3000 feet long and from
25 to 100 feet thick, is about H miles east of Bagby and about 1 mile
north of the Merced River. The deposit, sometimes called the Welch
and Farney deposit (Logan, 1947, p. 253), is undeveloped and nothing
is known of its chemical or physical characteristics. Small pendants of
limestone in granitic rock are reported in the Ben Hur district of
southwestern Mariposa County but these are undeveloped.

Figure 56. One of several muscovite schist quarries along-
Brushy Canyon in the White Rock district. The rock was ground
and used as a lubricant in manufacture of rubber tires. The schist
is derived from rhyolite tuff of the Cosumnes member of the Upper
Jurassic age.
Magnesite
There is one known occurrence of magnesite in the vicinity of Mor-
mon Bar. There, several narrow magnesite veins are found in weath-
ered serpentine associated with siliceous hot spring deposits (Laizure,
1928, p. 148). No magnesite has been produced in the county and the
occurrence is not believed to be sufficiently large to be of economic
importance.
Mica
There are large deposits of muscovite-quartz schist in the Brushy
Canyon vicinity of the White Rock district 2 miles north and slightly
west of White Rock School. The schist has formed from metamorphism
or rhyolite tuff of the lowest member of the Upper Jurassic Mariposa
group (Taliaferro, N. L., personal communication, 1938). It occurs
in at least two northwest trending (N. 55-65° W.) belts that dip steeply
northeast. The width of the relatively clean, pearly white schist ranges
from 40 to over 100 feet and, in the main zone has a strike length of
at least 1^ miles. The main zone is repeated at least once by folding,
so that there are two or more subparallel zones separated by several
hundred feet of schistose rocks of much lower muscovite content.
Numerous pits and several small quarries expose a considerable ton-
nage of uniform rock in which quartz is the only major mineral other
than muscovite. Several million tons of material could be developed.

Figure 57. Detail of the quarry face in the muscovite schist
quarry shown in figure 56. The lightest bands are quartz-rich rock
which in places is a troublesome impurity.
The quality of the material is dependent upon the proportion of quartz
present, for most uses, and insufficient testing has been done to estab-
lish the amounts of rock of various grades that are present. There was
a small, intermittent production of the schist in the 1930 's and 1940 's
principally for use as a lubricant in manufacture of automobile tires.
So far as the authors know, there has been no production since 1946.
There is one quarry on the main schist zone 15-20 feet wide, 85 feet
long and 20-30 feet deep.
A series of open cuts extends north from the main quarry over 400
feet. There are also several pits northeast of the main workings about
a quarter of a mile away.
Ornamental Stone
The brightly colored, green variegated mariposite-ankerite-quartz
rock from Mother Lode and adjacent vein systems has been finding
favor, in recent years, as an ornamental stone in gardens, patios and
the like. It has been quarried recently along Highway 49 between
Bagby and Coulterville near the Specimen group of gold mines and
near the Virginia and Mary Harrison mines. Production has been
intermittent because of vagaries of demand and because the select,
unstained mariposite rock tends to occur in small masses. The chief
detrimental impurity is discoloring iron oxide derived from original
sulfide minerals. Select rock brings 20 to 30 dollars a ton on the retail
214 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
market but selective mining and hand sorting make the initial cost of
production high.
Rock, Sand and Gravel for Aggregate
An intermittent production of rock, sand and gravel has been re-
corded from Mariposa County since 1907. During the period of opera-
tion of the Yosemite Valley Railroad there was a substantial production
of chert and greenstone for road metal, road base and railroad ballast
from quarries near the present location of Exchequer Lake. All activity
there ceased in 1944. Sand and gravel deposits in Chowchilla Creek,
Mariposa Creek and the Merced River between El Portal and Brice-
burg have been exploited intermittently in a small way for many years.
The rock particles making up these deposits consist predominantly of
ancient, dense, volcanic porphyries, quartzite, vein-quartz and numer-
ous varieties of crystalline metamorphic rocks, but in the Ben Hur-
Chowchilla Creek area the deposits are predominantly of granitic rock-
debris.
The extensive dumps of many of the mines along Highway 49 have
been utilized in quantity, from time to time, for fill, road base and
macadam. Such rock has also been used sparingly in concrete although
not generally as satisfactory as stream gravel. Extensive deposits of
quartz sand, the product of the mills operated for gold ore, have
yielded substantial tonnages of material for concrete and plaster.
The dumps of the old Princeton and Mariposa mills have been nearly
depleted of such material. There is a huge dump of crushed quartz
south of the Merced River at Bagby but it is not readily accessible
and is a considerable distance from potential markets. Inasmuch as the
population of Mariposa County is only about 5000 and inasmuch as
the mileage of state highways and other surfaced roads is relatively
small, there has been little incentive to develop the vast reserves of
hard, durable rock found within the county. These include the granites
of the Cathay, El Portal, Mormon Bar, Ben Hur, and Schultz Moun-
tain districts; the cherts and greenstones of the Hornitos Bear Valley
and Coulterville districts; and the crystalline limestones and dolomites
of the Briceburg, Hite Cove and Bower Cave districts.
Mariposa Sand and Gravel Company. This company, a partnership
of George P., J. G. and E. C. Greenamayer, operates out of Mariposa
and in recent years has operated a crushing and screening plant on
Mariposa Creek opposite the fair grounds 1^ miles south of Mari-
posa. Much of the material processed consists of old dredge tailings.
A steady, substantial production has been maintained over the past
5 years or more. The company also produces a little by-product gold
and silver.
Other Producers in the Vicinity of Mariposa. W. J. Saye of Mari-
posa has produced sand and gravel in recent years from shallow deposits
on Humbug Creek 2| miles south of Bootjack. These deposits are chiefly
weathered granitic rock that has been moved only a short distance by
flood waters of Humbug Creek. In past years the Duke Brothers have
produced sand and gravel from Chowchilla Creek about 7 miles south
of Mariposa. Paving contractors such as George E. France, Ralph Max-
well and the Piambo Construction Company produce rock intermit-

tently using portable crushers that can be moved to deposits adjacent
to their various jobs.
Roofing Granules and Terrazzo Chips
There has been considerable demand, in recent years, for colored,
durable rocks for use on built-up, asphalt-base roofs. The red and yel-
low jasperoid chert of the Jasper Point district would undoubtedly be
suitable for this use if satisfactory roads were constructed to the
vicinity. No work has been done on them since discontinuance of serv-
ice on the Yosemite Valley Railroad. The massive greenstones of the
Sierra foothills have been utilized in other counties for granules but
so far none of the Mariposa County deposits have been activated.
For the past year or two, dark green serpentine has been quarried
by the Sonora Marble Aggregates Company from a roadside quarry on
Highway 49 approximately 2-J airline miles northwest of Bagby. The
quarry is in the NWJ, sec. 19, T. 3 S., R. 17 E., M.D. About once a
month the company trucks several loads of serpentine to their crush-
ing and sizing plant at Shaws Flat near Sonora, Tuolumne County.
The serpentine is dense and tenacious and has about the same hardness
as marble. Production of terrazzo chips in California is pretty well
limited to limestone, marble and serpentine because of the way in which
the chips are used. Terrazzo walls and floors are made by setting the
chips in light-colored, fine-grained concrete and then polishing the sur-
face with carborundum wheels. Materials harder or less tenacious than
marble are unsuitable inasmuch as grinding of hard materials is ex-
cessively costly and use of materials of mixed hardness tends to yield
an uneven polished surface.

Figure 59. LeGrand (White Rock) silica quarry in southwestern
Mariposa County just north of the Ganns Creek (LeGrand-Mari-
posa) road. Between 1942 and 1952 Kaiser Aluminum and Chemical
Company produced approximately 148,000 tons of quartz for use in
manufacture of ferrosilicon.
Silica
Vein-quartz has been quarried from massive deposits in western
Mariposa County for the manufacture of ferrosilicon and, to a minor
extent, for chemical and metallurgical use. Between 1942 and 1952 the
Kaiser enterprises quarried 147,964 tons of quartz from their White
Rock (LeGrand) deposit in sec. 14, T. S., R. 17 E., M.D., for use at
their Permanente ferrosilicon plant. This operation was discontinued
as the wartime government demand for ferrosilicon fell off. Prior to
j 942 there had been a small intermittent production of vein quartz for
miscellaneous uses, chiefly in the late 1920 's.
There are large deposits of vein-quartz cutting the slate belt that
lies between Mariposa and Planada. Unlike the vein matter in the
Mother Lode, most of this material is low in sulfides and carbonates
and would be a suitable source of high-grade silica. The deposits, how-
ever, tend to be of very irregular shape and often require expensive
selective quarrying. The potential reserves of silica in this part of Mari-
posa County run into many millions of tons.
Slate
In common with several other Sierran foothill counties, Mariposa
County has immense reserves of black slate suitable for roofing sheets,
flagstone and roofing granules. Good quarry sites can be found in all
of the three main metasedimentary units in the county, the Paleozoic

Calaveras group, the Upper Jurassic Mariposa slate and in the slaty,
tuffaceous parts of the Upper Jurassic Amador group. All of these
rock units have broad distribution in the county. At least 20 percent
of the land area of Mariposa County is underlain by slate and there
are innumerable places where sound, cleavable material can be quarried.
Because of the high cost of construction of buildings that are to be
roofed with slate there has been no demand for roofing slate in Cali-
fornia in recent years. Crushed slate granules for built-up, asphalt-base
roofs are used to some extent in California but have not been produced
in Mariposa County within the last decade. The most probable outlet
for slate at the present time is for flagstone for California 's flourishing
construction industry. The use of flagstone for building facings, patios
and ornamental walls and walks is ever-increasing and although black
rock is not in as great demand as the light-colored or strongly colored
sandstones and volcanic rocks of Arizona, Nevada and other parts of
California, the consumption of slate is sure to increase. Up to the pres-
ent time there has been no vigorous attempt to put slate flagstone onto
the California market. Inasmuch as slate is softer and has a greater
tendency to spall than many other kinds of flagstone it is necessary to
select the soundest material available in order to successfully compete
with these other materials.
During the early part of the present century sheets of good roofing
slate were produced by the Cunningham Corporation of Planada from
a property covering sections 6, 7, 8 and 17, T. 7 S., R. 17 E., M.D.,
astride Mariposa Creek 6 airline miles south of Cathay. At about the
same time roofing-slate sheets were also produced :by Pacific Slate
Company of Merced from a property in sec. 16, T. 6 S., R. 16 E.,
M.D., about 3 miles southwest of Indian Gulch (Laizure, 1928, p. 151).
There is a series of small quarries on the northwest side of Highway
140, the Yosemite All Year Highway in sections 2 and 3, T. 7 S., R. 16
E. and sec. 35, T. 6 S., R. 16 E., M.D. These quarries are less than
2 miles from the intersection of the highway with the Mariposa-Merced
County line and 7 miles from the railroad at Planada.
The only slate property that has produced flagstone in recent years
is in sec. 21, T. 5 S., R. 18 E., M.D., at the north end of Nigger Hill
close to Agua Fria Creek and Highway 140 approximately 9 miles by
road from Cathay. There has been a small intermittent production of
flagstone from this place sold locally and called for by the customer.
Formerly part of Las Mariposas Grant the property is now separately
owned.
Talc, Pyrophyllite and Soapstone
Talc occurs at numerous places in Mariposa County as a hydro-
thermal alteration product of serpentine. It is found in and adjacent
to many of the quartz veins that cut serpentine but is also found along
shear zones in serpentine not associated with quartz veins. Because
most of the talc formed by alteration of serpentine contains consider-
able iron it cannot be used for most ceramic purposes, and its usefulness
is limited to such products as lubricants, insecticides and, when suf-
ficiently pure and white, cosmetics. Up to the present deposits that are
larger and nearer the marketing centers have supplied most of the
requirements of the California market in talc of the lower grades, but
Nos. 1 and 2] mines and mineral deposits, mariposa county 219
some of the Mariposa County occurrences may be used in the future.
There has been no systematic exploration or testing of any of the Mari-
posa County deposits to determine the extent and quality of the mate-
rial available. Most of the occurrences discovered thus far in the county
are in the Flyaway Gulch vicinity of the Bagby district.
Talc rock or soapstone was used all along the Mother Lode in the
early days for building facings as it looked good and was easy to shape.
Talc for this purpose was produced in the hills east of Mariposa and on
Greeley Hill east of Coulterville.
Pyrophyllite in beautifully crystallized rosettes occurs with quartz on
Three Buttes (Tres Cerritos) 2 miles southwest of Indian Gulch. It has
developed by hydrothermal alteration of greenstone of the Upper
Jurassic Amador group along a northwest-trending shear zone. The
pyrophyllite is too intimately mixed with quartz to allow selective
mining and the total pyrophyllite content of the quartz mass is low.
Presence of iron oxide from altering pyrite also detracts from the eco-
nomic value of the deposit. The pyrophyllite-bearing zone is at least
half a mile long and 20 to 40 feet wide.

ABSTRACT
Oxidized lead-zinc-silver ores in the desert ranges of southeastern California were
first worked for their silver content. The zinc-copper ores of the Sierra Nevada
foothill belt and the Shasta district were discovered below iron-rich gossans which
were being worked for their gold content. From 1871 through 1953 California mines
have yielded 447 million pounds of lead of which Inyo County has accounted for
94 percent. Of this total, 50 percent has been produced since 1942. California's
annual production of lead since 1942 represents about 2 percent of the annual
national total production. Through 1953 the total zinc production was 267 million
pounds of which 55 percent came from the Shasta district, 28 percent from the Basin
Ranges of southeastern California, and 15 percent from the Sierra Nevada foothills.
The occurrence of commercial lead and zinc in California is confined largely to
three geological environments, (1) faulted carbonate rocks of the Basin Ranges of
southeastern California, (2) zones of shearing in metavolcanic rocks along the
Sierra Nevada foothills, and (3) fractured porphyritic rhyolite in the Shasta area.
Other occurrences of minor importance are the contact deposits and high tempera-
ture fissure veins within metamorphic roof pendants in the high Sierra Nevada, and
the minor base metals which occur with the precious metals throughout the base
metal districts, along the Mother Lode, in the East belt, and the Klamath Mountains.
Five distinct mineralogical types of lead and zinc ores have been recognized in
California. These are: (1) lead-zinc replacement bodies in the carbonate rocks of
the Basin Ranges of southeastern California and in the Mojave Desert, (2) silver-
lead-zinc ores of the same districts, (3) zinc-copper, massive and disseminated sul-
fides in the metamorphic and volcanic rocks of the Sierra Nevada foothills and the
Shasta district, (4) complex copper-gold-lead-silver-zinc contact deposits and high
temperature fissure veins which occur mainly in the high Sierra Nevada and in
eastern San Bernardino County, and (5) precious metal deposits.
Distinct environments of deposition are recognized in the various districts. Struc-
tural and mineralogical settings are fairly constant within each of the districts. In
the Basin Ranges and Mojave Desert silicated carbonate rocks are the principal
hosts. Selective replacement of silicated and dolomitized rock is evident. The principal
structural settings are fault blocks, igneous contacts, and thrust faults. In the Sierra
Nevada foothills zinc and copper sulfides selectively replace pyritized and silicified
metavolcanic rocks along the foothill shear zone which marks a major break between
the uplifted Sierran block and the down-dropped geosyncline which forms the Great

Valley of California. In the Shasta district massive zinc-copper sulfides occur along
high angle faults, horizontal tension openings, and selective beds in porphyritic
rhyolite.
The mining and processing of the various types of ore differs widely. Zinc-copper
ores have required milling and flotation to produce marketable concentrates. Heavy
ground at most deposits has required much timbering and back filling. The lead-zinc-
silver ores have, in the past, been of shipping grade ; however, in recent years flota-
tion following sulfidization of the oxidized ore has been used on the large low grade
deposits. Because the carbonate rocks stand well without timbering, open stopes
predominate. The selective mining of shipping grade ore at the smaller deposits has
resulted in very irregular workings and the abandonment of low grade ore in old
workings. The precious metal deposits, in general, occur in badly fractured ground
and square-set timbering and back filling have been required. Base metals recovered
from these ores have come from concentrates and high grade ore shipped to smelters.
Most of California's lead-zinc ore and zinc concentrate have been smelted in Utah.
Zinc and copper concentrates from zinc-copper ores have also been shipped out of
state, mainly to Great Falls and Tacoma. The bulk of the precious metal ores and
concentrates as well as a portion of the high grade lead ores and concentrates have
been smelted in California at Selby.
INTRODUCTION
Documentary information on lead and zinc mining in California is
widely scattered through scientific literature, commercial files, and pub-
lications of the State and Federal governments. The purpose of this
report is to bring together the available information, and to present it
in abstracted form in order to encourage systematic development of
California lead and zinc resources.
Detailed descriptions of most of the old mining camps are lacking
and, commonly, the only available information consists of statistics
on production. During the national emergency of World War II the
Federal government, through the facilities of the U. S. Geological Sur-
vey and U. S. Bureau of Mines, began a program of exploration for
critical minerals. Systematic examination of potential copper produc-
ing areas began; mines along the Foothill belt were mapped in detail,
and some were diamond drilled. The results of these examinations were
published in 1948 in California State Division of Mines Bulletin 144,
prepared under the direction of Olaf P. Jenkins. This volume is a
comprehensive report on the zinc-copper deposits of the Sierra Nevada
Foothill belt. Another cooperative work program between California
Division of Mines and the U. S. Geological Survey has been a study
of the zinc-copper deposits of the Shasta district. California Division
of Mines Special Reports on four massive sulfide deposits have been
published to date (Kinkel and Albers, 1951, Kinkel and Hall, 1951,
Kinkel and Hall, 1952, Albers, 1953) and the entire project is nearing
completion. Further work under the cooperative program is in prog-
ress along the Sierran Foothills, in the high Sierran region, and in
the Basin Ranges. The Darwin quadrangle has been mapped and de-
tailed work has been done at the Cerro Gordo mine, (Merriam, 1949),
Santa Rosa mine (Mackevett, 1953) and Lippincott mine (McAllister
and Mackevett, 1949) in the Ubehebe district. Other lead-zinc deposits
in this area will be mapped in detail.
The Darwin district has been mapped in considerable detail and the
geology and ore deposits described (Kelley, 1938). Except for the
above work, detailed mapping has largely been done by operating
companies.
Nos. 3 and 4] lead and zinc in California 355
During the course of this examination, typical deposits in each of
the mineralized districts were examined and known sources of available
information were consulted.
Lead and zinc deposits that have proved to be commercial are con-
centrated in three principal districts ; the Basin Ranges of Inyo County,
the Sierra Nevada foothills from Fresno County north through Butte
County, and in the vicinity of Redding in Shasta County. Other scat-
tered deposits of less importance are located in the eastern portion of
the Mojave Desert in Riverside and San Bernardino Counties, in Impe-
rial County, Orange County, on Santa Catalina Island, in the high
Sierra Nevada in Mono, Inyo, Madera, Fresno, and Tulare Counties,
and in the Mother Lode and East belt gold districts.
The occurrences of lead and zinc in complex mineralogical assem-
blages makes classification of ore types difficult. For simplicity only
two main types have been distinguished on the mineral map and in
the tabulated section. These are zinc-copper ores and lead-zinc ores.
The author wishes to acknowledge the assistance and cooperation of
the U. S. Geological Survey, U. S. Bureau of Mines, mining companies,
and mine owners and operators throughout the state.
HISTORY OF MINING1
Lead. The first lead mined in California was by Mormons working
silver deposits in the southern Panamint Range, Inyo County. The rich
silver-lead deposits of Cerro Gordo, discovered by Mexicans in 1862,
were first worked primarily for silver; ore was smelted in vasos. In
1869, American interests erected two smelters at the mine and a third
smelter at Keeler on the shore of Owens Lake. In 1876 the Santa Maria
and Union mines were consolidated to form the famed Cerro Gordo
mine. By 1877 the rich oxidized near-surface ores were depleted and
activity declined until interest was revived by the completion of the
railroad to Keeler about 1880.
Darwin, an equally famous silver camp, was discovered in 1874 and
by 1880 several mills and smelters were in operation. Water was piped
from the Coso Mountains, a distance of about 8 miles. During the early
period when rich oxidized silver ores were being mined, Darwin was
a flourishing town of about 5,000 people. The richer ores were soon
depleted at both Darwin and Cerro Gordo and a drop in the price of
silver in 1893 closed many of the mines.
Subsequent operation at Darwin was intermittent during periods
of great demand until 1945 when Anaconda Copper Mining Company
purchased the major holdings. Production has averaged 8000 to 10,000
tons of ore per month in recent years.
About 1880, silver-lead ore was discovered on the east flank of the
Argus Range in what is now known as the Modoc district. By 1890 the
principal mines, the Modoc and Minnietta, had boosted Inyo County's
mineral production by $3,000,000.
Zinc. Zinc mining in California began, in part, as an outgrowth
of copper mining which in turn resulted from the search for gold in
the iron-rich gossans along the Sierra Nevada Foothill belt and in the
Shasta district. Mining along the Foothill belt began in 1860 when

Quail Hill was located as a gold prospect. Below the gossan, rich
copper ores were found and the enriched ores were shipped to Swansea,
Wales, for smelting. By 1863 the Napoleon, Empire, Union, Keystone,
North Keystone, Campo Seco, Lancha Plana, Copper Hill (present site
of Penn mine), and the Newton mines had been discovered. These dis-
coveries were soon followed by the Spenceville, Collier, La Victoria,
Green Mountain, Lone Tree, and Buchanan, and copper mining along
the Foothill belt was in full swing. Most of the enriched copper ore
had been mined out by 1867, and between 1868 and 1881 most of the
mines were inactive because of the high cost of freight to Swansea and
the decrease in gold-silver content below the gossans. Not until 1906
was zinc recovered from the Foothill copper ores; previously, it was
considered a nuisance. Copper ore had to average 15 percent copper to
pay expenses to "Wales. Activity revived slightly in 1882 and again in
1902 to 1920 and 1924 to 1930. Government subsidies and cooperation
in exploration revived the Sierra Nevada Foothill belt during World
War II and more than 25,000,000 pounds of zinc and 22,000,000 pounds
of copper were produced between 1942 and 1946. About 12 complex
sulfide mines in 8 counties along the Foothill belt were in operation
using improved selective flotation methods. Two new zinc mines were
developed as a result of diamond drilling of gossans in the Foothill
belt by the U. S. Bureau of Mines. These were the Blue Moon mine in
Mariposa County and the Big Bend mine in Butte County. Total pro-
duction of the Foothill belt from 1860 to 1946 was more than 200
million pounds of copper and 40 million pounds of zinc in addition
to a large gold-silver, and minor lead recovery.
Copper mining in the Shasta district began in 1894. The Keswick
smelter was erected to treat ores from the Iron Mountain mine. In
1904, U. S. Smelting Mining and Refining Company took over the
Mammoth, Balaklala, and Keystone mines and built a smelter at Ken-
nett which operated until 1924. Zinc was not recovered from Shasta
County copper ores until 1913 and no significant production resulted
until 1915 when General Electric Company built an experimental elec-
trolytic zinc plant at Winthrop. The recovery of this plant was 300
to 400 pounds of zinc per day. Between 1917 and 1918 electrolytic zinc
was produced from smelter fumes by Mammoth Copper Company at
the Kennett smelter. In 1918 electrolytic zinc was being produced at
the Winthrop plant from zinc-rich ores from the Afterthought and
Bully Hill mines. Milling of Bully Hill and Afterthought zinc-copper
ores was unsuccessful as the copper concentrates contained too much
zinc. In June 1922, Shasta Zinc Company built a reverberatory fur-
nace and zinc oxide plant at Bully Hill to treat these complex ores.
The plant operated until December of the same year when the price
of zinc oxide dropped. The California Zinc Company took over the
operation of the Afterthought and Bully Hill mines in 1924 and
abandoned the smelting and zinc oxide operations. This company
shipped a bulk concentrate containing 43-49 percent zinc, 3.7-4.1 per-
cent copper, 7-11 percent iron, 1.3-1.7 percent lead, and 2.3 percent
silica to Belgium for treatment. During this same period concentrates
from the Black Jack mine on Santa Catalina were also being shipped
to Belgium. By 1928 a drop in the price of zinc closed most of the
Shasta County mines as well as the Sierra Nevada Foothill mines.
Nos. 3 and 4] lead and zinc in California 359
From 1928 to 1943 the entire zinc production was from lead-zinc ores
in southern California.
Zinc mining as such in California began at the Cerro Gordo mine in
1907 when large bodies of secondary zinc carbonate were found in
the footwalls of the old lead stopes. Between 1911 and 1915 a large
tonnage of pure zinc carbonate was mined. By 1949 this mine had
yielded more than 23 million pounds of zinc. With the exception of
those from the Cerro Gordo mine, shipments of straight zinc ore have
been rare. At many mines zinc ore was left in the stopes since it could
not be mined profitably. Not until the advent of selective flotation did
zinc become an important by-product or co-product in lead-silver-zinc
ores and in copper-zinc ores.
GENERAL GEOLOGY OF THE MINING DISTRICTS IN
RELATION TO LEAD AND ZINC
Basin Ranges. The Basin Ranges of California lie at the extreme
southwestern edge of a large geomorphic province of fault-block desert
ranges that occupies most of Nevada and a large part of Utah and
Wyoming. The province is characterized by a thick accumulation of
carbonate rocks with interbedded slates and quartzites deposited in
inland seas that covered the area almost continuously from early Paleo-
zoic to late Mesozoic time. These rocks were folded during the Nevadan
revolution in late Jurassic time and large scale thrusting occurred
during the Laramide revolution beginning in early Cretaceous time.
Thrusting and upbowing was followed by a period of relaxation during
mid-Cretaceous time when normal faulting began and small bodies of
granitic intrusive rocks were emplaced along lines of structural weak-
ness. Large scale dolomitization of limestone and ore mineralization
followed. These normal faults were again active during Miocene time
when they served as vents for the outpouring of large sheets of basic
to acidic lavas. Basin Range orogeny culminated in Pleistocene times
when large normal and reverse movements, along the old faults, brought
equilibrium to this large upbowed arch, leaving north-trending fault-
block mountains and intervening downdropped basins. These ranges,
with their lava-capped back slopes, rise above the alluvium-filled valleys.
The principal metallogenic period in the Basin Range country fol-
lowed the thrusting and early normal faulting about mid-Cretaceous
(?) time. Medium to low temperature replacement deposits of lead-
zinc, silver-lead-zinc, and higher temperature contact and vein deposits
of complex copper-lead zinc with associated scheelite, as well as part
of the siliceous gold-silver veins with associated lead, zinc, and copper,
were formed during this time. A less important metallogenic epoch
in late Tertiary (Mio-Pliocene) followed a period of unrest during
which time lavas capped the embryonic Basin Ranges. This period of
metallization appears to be related to the emplacement of small gran-
itic stocks throughout the Basin-Ranges country. The deposits of this
period are mainly gold-silver which occur as siliceous veins in altered
volcanic rocks or within the small Tertiary (?) stocks. Minor propor-
tions of lead, zinc, and copper sulfides are commonly associated with
these ores.
Mines in the Basin-Ranges province in California have produced
approximately 94 percent of the lead and 28 percent of the zinc pro-
duced in California to date.

Shasta Zinc-Copper District. The Shasta zinc-copper district lies
at the north end of the Great Valley of California, in the southwest
corner of a large volcanic province which occupies most of Lassen and
Modoc Counties. This volcanic province not only obscures the bedrock
geology of the northern Sierra Nevada but has hindered correlation
of Sierran rocks with those of the northern Coast Ranges and Klamath
Mountains.
The Shasta district is divisible into two units, the East and West
Shasta districts. This division is not only geographical but lithological
and structural as well.
In the West Shasta district Paleozoic meta-volcanic rocks, meta-sedi-
mentary rocks, and interbedded volcanic rocks are folded into a broad
arch trending N. 15° E. This faulted arch, which plunges north, is
intruded by late Jurassic granite and quartz diorite. Ore occurs as
massive sulfide replacements in Balaklala rhyolite of Devonian (?)
age. Mineralization is believed to be related to the late Jurassic intru-
sions (Albers, 1953).
In the East Shasta district Mesozoic volcanic rocks and meta-sedi-
mentary rocks are compressed into a series of asymmetrical folds which
trend from N. 70° W. in the eastern part of the district to north or
N. 10° E. in the western part (Albers and Robertson, 1952). The dis-
trict is broken by thrust faults and normal faults trending from north
to N. 70° W. Diabase and soda rhyolite dikes intrude the sequence.
Massive sulfide replacements occur along shear zones in Bully Hill
rhyolite of middle or late Jurassic age. The metallization is believed
to be related to deep lying igneous rocks of Jurassic ( ?) age.
In the Shasta district Coast Range rocks which in general strike
north to northeast are in contact with Sierran rocks which strike north-
west. This fact may be of critical importance in explaining the appar-
ent structural favorability of this area to mineralizing solutions.
To date, mines of the Shasta district have produced about 42 percent
of California's total zinc output.
Foothill Belt. The Foothill belt is defined geographically as a zinc-
copper district along the western slope of the Sierra Nevada from
Fresno County in the south to Butte County on the north. It marks a
zone of faulting and shearing in Paleozoic and Jurassic slates, schists,
and meta-volcanic rocks, and marks a major structural break between
the Sierran uplift and the San Joaquin-Sacramento Valley. This shear-
ing was part of the sequence of deformation and igneous intrusion that
built the Sierra Nevada in late Jurassic time.
Igneous activity began by the intrusion of ultrabasic rocks and
ended with the emplacement of the Sierra Nevada granitic batholith
with its associated aplitic and pegmatitic dikes. The earlier emplaced
basic and ultrabasic rocks were metamorphosed by these later intrusives
and by continued deformation. Alteration in the form of chloritization
and serpentinization was most common. Locally along shear zones and
faults alteration by silicification, pyritization, and sericitization was
strong. The sulfides of copper and zinc accompanied and followed the
introduction of pyrite along some of these faults. The most favorable
rocks for replacement by the sulfides were chloritized and sericitized
breccia along shear zones. Local silicification was intense along the
entire belt of shearing.
Nos. 3 and 4] lead and zinc in California 361
The Foothill belt has been an important source of zinc only during
periods of great demand because of the smallness of deposits, re-
fractory nature of the ore, and high cost of transportation. Neverthe-
less the Foothill belt has contributed more than 40 million pounds, or
15 percent of California's total zinc output. Most of this was produced
between 1942 and 1946 under the stimulus of high prices, governmental
cooperation, and improved flotation techniques. A large but unproven
potential reserve in the form of small, low grade complex deposits
probably exists along the Sierran Foothills.
Mojave Desert. The Mojave Desert, which occupies a large portion
of San Bernardino and Riverside Counties, is essentially an area of
crystalline metamorphic rocks and volcanic rocks intruded by granitic
stocks. The province is bounded on the north by the Garlock fault and
on the southwest by the Transverse Ranges. To the east it is ill-defined
and merges with the Basin-Ranges province where north-south fault
block mountains predominate.
Mineralization is almost identical with that of the Basin-Ranges
province. Lead-silver-zinc replacement bodies in carbonate rocks are
the dominant type. Complex sulfides of copper, lead, and zinc with
associated scheelite are scattered through this district and are concen-
trated in the extreme eastern part of San Bernardino County. Two
precious metal districts are of importance in this area; these are the
Mojave gold district and the Randsburg silver district. Each has been
a source of by-product lead.
To date the mines of the Mojave Desert area have produced an esti-
mated 4 percent of the state's total lead and an estimated 1J percent
of the total zinc production.
High Sierra Nevada. The high Sierra Nevada province includes
the western portions of Mono and Inyo Counties, along the Sierran
fault scarp, and the eastern portions of Madera, Fresno, and Tulare
Counties. The southern Sierra Nevada batholith with its pendants of
metamorphic rocks is host to a unique group of contact deposits. Ero-
sion has stripped the metamorphic cover from the batholith; all that
remains are the deeply infolded roof pendants. Within the pendants
limestone, slate, and schist of pre-Cretaceous age predominate. These
rocks have been recrystallized by plutonic and regional metamorphism.
Metasomatic changes have been strong in many localities. Slates and
schists have been recrystallized and silicified. Limestones have been
recrystallized and with the addition of silica have been transformed
into a variety of lime silicates.
It is within these zones of strong metamorphism and silication that
high temperature contact deposits have formed. Sulfide mineralization
is sparse but widely distributed. The principal deposits of this province
are complex sulfides of copper, lead, and zinc, often in association with
scheelite and minor amounts of gold and silver.
Production from this district has been small and most of the de-
posits, because of their inaccessibility, haven't been developed beyond
the prospect stage. High altitudes and short working seasons have hin-
dered development. Elevations range from 5000 to over 12,000 feet.
Mother Lode. The Mother Lode belt is a zone of reverse faulting
and shearing which lies between and parallel to the Foothill belt and
362 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
the East belt at an average elevation of about 1500 feet. The Paleozoic
complex is here overlain by Mesozoic slates and metavolcanic rocks,
and is intruded by basic to ultrabasic rocks emplaced prior to the
Sierran batholith proper. Small granitic stocks and apophyses from
the Sierran batholith are also present and in some localities appear to
be genetically related to the gold deposits. The obvious relationship
between Mother Lode mines and the belt of basic to ultrabasic rocks
is believed to be structural and not genetic. The early basic differentiates
appear to have been emplaced along the major breaks which flanked the
Sierran uplift on the west side. Silica- and gold-bearing solutions later
followed these same lines of weakness. Mineralization in Mother Lode
mines as opposed to East belt mines, extends to and beyond the eco-
nomic limits of mining. The temperature of mineralization, in general,
appears to be slightly lower in the Mother Lode. The principal gangue
minerals are quartz, chlorite, pyrite, and arsenopyrite. Galena and
sphalerite are less conspicuous than in the East belt. Appreciable quan-
tities of lead have been recovered at the Selby smelter near San Fran-
cisco from the large volume of gold ores and concentrates produced
along the Mother Lode.
East Belt. The East belt gold district lies at an elevation of 2000
to 4000 feet at an average distance of about 8 miles east of the Mother
Lode from Mariposa County north through El Dorado County.
Gold-bearing quartz veins at or near contacts between the Sierra
Nevada batholith and Paleozoic meta-sedimentary rocks appear to be
higher temperature deposits than the Mother Lode proper. Host rocks
are both Paleozoic meta-sedimentary rocks and the intrusive granite.
Mineralization extends to shallow depths along fractures which appear
to be related to cooling and shrinkage along the periphery of the batho-
lith. Lead and zinc sulfides are very conspicuous and the higher-grade
gold ores usually contain about 1 or 2 percent lead. Contact minerals
such as garnet and epidote are commonly conspicuous gangue minerals
and some of the deposits contain appreciable amounts of scheelite.
The production of lead from the East belt has been small but con-
stant, and has been obtained both from concentrates and from high-
grade ores which were shipped to the smelter at Selby.
MINERALOGY OF DEPOSITS AND ENVIRONMENTS OF DEPOSITION
Mineralogic Types
Lead-Zinc. The lead-zinc and zinc-lead deposits of the Basin-
Ranges province and eastern portion of the Mojave Desert are by far
the most important producers in California. They have accounted for
94 percent of the lead and 28 percent of the zinc produced in Cali-
fornia. The apparent predominance of lead over zinc is misleading
because most of the deposits contain equal amounts of lead and zinc.
Prior to 1900 lead was mined selectively and zinc-rich ores were avoided
and left in the stopes. Of the ore mined and smelted the zinc was not
recovered. Most of it went into the slags and much was lost, along with
lead, as flue dust. Even now with improved techniques in selective
flotation lead-poor ores are marginal and much zinc is being left in the
stopes. Many of the early smelter slags ran as high as 15 percent zinc
at such camps as Cerro Gordo and Darwin. Zinc always commanded a
Nos. 3 and 4] lead and zinc in California 363
lower price and the smelting of zinc is complicated and expensive; so
much so that the mine operator 's return from smelters has discouraged
the development of zinc stopes. On the other hand, ores that run excep-
tionally high in zinc will bear shipping and at some mines zinc has been
the principal product.
All lead-zinc and zinc-lead ores contain silver and gold in varying
amounts but average less than 10 ounces of silver per ton. Ores with
10 or more ounces of silver can be mined for their silver content alone,
during economically favorable periods. Milling grade ores that average
about 6 to 8 percent lead contain from 1 to li ounces of silver for each
percent of lead. Shipping grade ores (direct smelting) often contain
a much higher ratio of silver, for two reasons : 1 ) most shipping ores
are from the oxidized zone where enrichment of silver as well as lead
has been brought about by solution and removal of zinc and gangue
material, and 2) commonly the ratio of ounces-of -silver to percent-of-
lead rises with an increase in the lead content. Darwin and Cerro
Gordo, for example, were known primarily as silver camps during the
early days when rich oxidized ores were being smelted. If Cerro Gordo
were operating today, milling grade ore probably would not exceed 10
ounces of silver. Cerro Gordo 's production has been largely from direct
smelting ores.
Gold and copper are usually present in variable amounts. Lead-zinc
ores do not average more than 0.08 ounces of gold and 0.25 percent
copper. Copper content appears to be inversely proportional to the zinc
content. In ores with 1 percent or more copper, zinc is commonly sub-
ordinate to lead and the gold value commonly exceeds the silver value.
These are, in general, higher temperature deposits, either contact or
fissure vein.
The principal primary ore minerals in lead-zinc deposits are galena
and sphalerite, with associated argentiferous galena, auriferous chal-
copyrite and pyrite. In the oxidized zone sphalerite and chalcopyrite
are rare; usually zinc and copper have been largely removed but may
be present in the form of smithsonite, calamine, malachite, and azurite.
Galena may persist, even in the outcrop ; however, most of it is changed
to anglesite, and finally to cerussite. Silver may remain in the oxidized
zone as finely divided native silver or as silver chloride or silver bro-
mide, however it may be transported out of the oxidized zone in the
form of soluble silver sulfate (in the absence of halogen ions) and
eventually be redeposited as a chloride, bromide, iodide, or as native
silver.
Carbonate rocks in the vicinity of granitic intrusions are the common
host for these deposits. Regional and plutonic metamorphism with
varying degrees of metasomatism preceded ore deposition. The usual
chain of events has been folding, faulting, and regional metamorphism
of the carbonate rocks, followed by igneous intrusion, silicification,
silication, and dolomitization especially at contacts and along major
faults. Ore deposition followed; in many districts minor adjustment
along faults was still going on. Ore bearing solutions also contained
silica, manganese, iron, and in some localities fluorine and barium.
These solutions followed the same planes of weakness followed by the
earlier dolomitization and silicifying solutions. The formation of the
lime-iron silicates such as epidote, garnet, diopside, and wollastonite,
364 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
was generally confined to the contact zones. In general the high tem-
perature deposits formed here are higher in pyrite and chalcopyrite and
some contain scheelite. Along the major faults away from igneous
contacts replacement bodies of argentiferous galena and sphalerite were
formed. These bodies preferentially replace dolomitized limestone and
in many deposits the solutions moved out laterally from the major
faults and replaced fresh limestone along flat-lying tension openings
and favorable beds.
The net result is, in general, high temperature contact deposits of
galena and sphalerite, with some chalcopyrite and pyrite, in a lime-
silicate gangue along contacts; and massive replacement bodies of
galena and sphalerite, with more silver and less chalcopyrite, in a
gangue of dolomitized limestone, jasper, manganese oxide, and in some
localities fluorite and barite. Fissure veins and bedding-replacement
deposits are found at some distance from the major faults in re-
crystallized limestone, beyond the dolomitized zone.
Silver-Lead-Zinc. Lead-zinc ores rich in silver attracted the first
miners to the desert ranges of California about 1859. The richest, near-
surface ores were mined selectively and crudely smelted to extract their
silver. With the exception of these early ores, which were also high in
lead, silver-lead-zinc ores have largely depended on their silver content
to meet shipping-grade requirements. Two extremes exist within this
classification; extremely rich silver ores where lead is insignificant as
at Blind Spring Hill, Mono County, and shipping-grade lead ores where
a moderate silver content is strictly a bonus as at the Modoc mine,
Inyo County. Intermediate between these two extremes fall most of
the deposits with moderate grade lead ores which depend on a silver
content of 10 ounces or more to pay for shipping. Thus silver-lead-zinc
ores grade into lead-zinc ores with a decrease in silver, and at the other
extreme grade into gold-silver deposits where only the precious metal
content is significant.
Generally the silver mineral in the primary ore is not identifiable
and it is commonly assumed that the silver is locked in the galena
molecule in solid solution. The silver is discernible only in the highly
oxidized ores where it occurs as native silver. Argentite, the sulfide of
silver, has been identified in many primary ores, but not in sufficient
quantity to account for the overall silver content.
Distinct groups of high silver ores are recognized at camps such as
Blind Spring Hill, Mono County, the Randsburg district in San
Bernardino County, and Cerro Gordo in part (the San Felipe vein).
These various hybrid types do not fall neatly into any scheme of classi-
fication. The principal primary silver minerals are freibergite, argen-
tite, and the complex silver-sulfosalts. In general these ores appear to be
later than the formation of the principal lead-zinc deposits. The San
Felipe vein at Cerro Gordo cuts the lead-zinc bodies at an acute angle.
The vein is siliceous in nature and barite is conspicuous in the gangue.
The principal primary silver mineral is freibergite. Mineralogy of the
Blind Spring Hill veins is very similar; however, the wall rock is
granitic. Freibergite, or argentiferous tetrahedrite, has been identified
in a barite gangue at many of the lead-zinc mines with high silver con-
tent. With more detailed work in the old districts, further classification
might be warranted.
Nos. 3 and 4] lead and zinc in California 365
The silver-lead-zinc deposits are scattered through the Basin-Ranges
and Mojave Desert provinces. Some occur in the High Sierra province
along with lead-zinc ores, where they grade into complex ores at and
near igneous contacts where chalcopyrite is common. A small cluster
of lead-zinc and silver-lead-zinc mines also occurs in Shasta County
around Igo and Ono, and in the Cow Creek and Battle Mountain
district in Permian and Triassic limestone near late Jurassic intrusives.
Zinc-Copper. The intimate association of sphalerite, chalcopyrite,
and pyrite distinguishes these ores from all others whether they occur
in massive sulfides as in the Shasta district or as disseminated sulfides
along shear zones as in the Foothill belt.
Exploitation of these deposits began in 1860 when the large gossans
were worked for gold. Enriched copper ores below the gossans led to
eventual development of the primary sulfides at depth. The refractory
nature of complex ores hindered their exploitation until the advent of
selective flotation.
The primary ore contains an intimate mixture of fine-grained sphal-
erite, chalcopyrite, and pyrite. Galena, gold, and silver are minor con-
stituents. The average grade of such ores is 8 to 14 percent zinc, 1.25
to 3.25 percent copper, 1 ounce to 5 ounces of silver, 0.016 to 0.065
ounce of gold, and up to 2 percent lead. Generally lead is much lower.
A hybrid type of apparently higher temperature origin does exist
in which chalcopyrite predominates and sphalerite content is low.
Pyrrhotite is present and may substitute for pyrite entirely. The gold
content rises proportionally with the copper, and silver is lower than
in the normal zinc-copper ores. These deposits grade into straight
copper ores. Island Mountain in Trinity County is a classic example
of this hybrid type.
Copper is persistent throughout the Foothill belt, zinc less so. Heyl
(1948) has divided the Foothill copper ores into the following four
(1) "Deposits made up of sphalerite, chalcopyrite, and pyrite, generally with small
amounts of galena and appreciable quantities of gold and silver. Examples : Big
Bend mine, Butte County ; Penn mine and Quail Hill mine, Calaveras County ;
Blue Moon mine, Mariposa County.
(2) "Deposits consisting mainly of pyrrhotite and chalcopyrite, with or without
pyrite and sphalerite, and generally with some gold or silver. Examples : Green
Mountain mine, Mariposa County ; Buchanan mine and Daulton mine, Madera
County ; Fresno copper mine, Fresno County.
(3) "Deposits of pyrite and chalcopyrite, with practically no gold or silver, and
with zinc minerals being absent or virtually so. Examples : Newton mine, Amador
County ; North' Keystone mine and Keystone-Union mine, Calaveras County.
(4) "Deposits composed of chalcopyrite, pyrite, and quartz, with or without
sphalerite and pyrrhotite, and generally with some gold and silver. Examples :
Eldorado copper mine, El Dorado County ; La Victoria mine, Mariposa County ;
Jesse Bell mine, Madera County."
In the Shasta district the mineralogy of the ores is very similar to
that of the Foothill ores and the tectonic and plutonic history is essen-
tially the same. The Shasta district may be considered the northwestern
extension of the Foothill belt.
The ore deposits of the Shasta District occur along steep-dipping
shear zones and along flat-lying bedding shears and tension openings
between steep-dipping normal and reverse faults. All of the larger
deposits occur in porphyritic rhyolite at or near its contact with non-
366 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
porphyritic rhyolite or tuff of different relative competency. Struc-
turally and chemically the Bully Hill and Balaklala porphyritic rhyo-
lites appear to have been exceedingly favorable hosts for ore-bearing
solutions.
Complex Ores. Complex ores occur as contact metamorphic and
high temperature fissure vein deposits. The primary ore minerals are
chalcopyrite, galena, and sphalerite, with appreciable gold and silver.
Scheelite is common.
The contact metamorphic deposits generally occur in tactite at lime-
stone-granite contacts or in silicified meta-sediments in contact with
granite. The common gangue minerals are lime-iron silicates, crystalline
calcite, magnetite, pyrrhotite, and pyrite.
The high temperature fissure veins are siliceous in nature and gangue
minerals differ with the host rock. In limy rocks the gangue minerals
are usually the same as in the contact metamorphic deposits. In siliceous
meta-sediments and igneous rocks, the gangue may be restricted prin-
cipally to pyrrhotite, pyrite, magnetite, and hematite.
Deposits of this class are generally small and have been worked in
the oxidized zone primarily for their gold content. They have not been
significant lead or zinc producers and where copper content is less
than 1 percent and gold accounts for the principal value, they have
been classed as precious metal mines.
High lead-zinc ores with 1 percent or more copper have also been
placed in this classification because of their possible genetic relation-
ship to high temperature mineralization. This relationship is demon-
strated by the eutectic intergrowth of chalcopyrite in sphalerite, and
by the character of the gangue minerals. The large lead-zinc replace-
ment deposits are conspicuously lacking in chalcopyrite except in the
contact zones where it may be accompanied by scheelite. Many of these
deposits were located originally as gold mines and ore from the oxidized
zone was cyanided. Some operators have shipped ore to copper or
precious metal smelters. The average tenor of such ores has been
about 3.5 percent copper, 7.8 percent lead, 12 ounces of silver per ton,
0.1 to 0.4 ounce of gold per ton, and minor zinc. Where gold exceeded
this amount and ore was obviously mined for its precious metal content,
the deposits have been classed as precious metal mines.
A great number of these deposits have recently been prospected for
tungsten, particularly in eastern San Bernardino County and Atolia
and Pine Creek tungsten mines may be included here.
These deposits are restricted mainly to the High Sierra Nevada
province and the Mojave Desert province in the eastern portion of
San Bernardino County adjacent to Arizona. They also are found near
intrusives throughout the Basin Ranges province. Other scattered local-
ities occur in Alpine, Nevada, and Plumas Counties. The concentration
of these deposits in eastern San Bernardino County appears to repre-
sent the western fringe of the great copper district of the southwest
United States.
Precious Metal Deposits containing Lead and Zinc. All gold mines
and silver mines known to contain galena and sphalerite have been
included in the tabulated section. Most of them have produced some
by-product lead from ores and concentrates smelted. Little or no zinc
Nos. 3 and 4] lead and zinc in California 367
has been recovered because most ores and concentrates were shipped
to smelters not equipped to recover zinc. Total production from these
siliceous ores has been small but the fact that many early gold mines
later developed into base-metal mines seems to warrant their inclusion
here.
Three subdivisional types of precious metal deposits are considered :
siliceous gold-bearing veins in base-metal districts, the late Jurassic ( ? )
gold-quartz veins in the Mother Lode, East belt, and Klamath Moun-
tains, and siliceous silver and gold veins of Tertiary age.
The siliceous veins in base-metal districts are by far the most im-
portant because their potential of producing lead, zinc, and copper is
greater than all other precious metal deposits. Most of these deposits
occur in the Mojave Desert and Basin Range provinces. Siliceous gold
bearing veins at and near the intrusive contacts contain various pro-
portions of the base metals. They appear, in general, to have formed
later than the lead-zinc replacement deposits, in the cooled and frac-
tured portions of the Basin Range stocks. The maximum base-metal
content is 3 percent copper and 10 percent combined lead-zinc.
The late Jurassic (?) or early Cretaceous gold-quartz veins of the
Mother Lode, East belt, Nevada City-Grass Valley district, and Klam-
ath Mountains have contributed a significant amount of lead, espe-
cially during the 1930 's when the production of gold ore was high.
Galena is much more abundant in the East belt and Nevada City-Grass
Valley districts, and in places forms the principal metallic gangue along
with pyrite. Mother Lode ores more commonly have less galena and
sphalerite, and more pyrite and arsenopyrite. The maximum base-metal
content of these ores is about 1 percent combined copper-lead-zinc.
Three gold mines in Nevada County are known to have produced
more than 100,000 pounds of by-product lead; these are the Empress,
Lava Cap and North Star. The Spanish mine in Nevada County has
produced more than a million pounds of combined lead-zinc. The
Alabama mine in Placer County and the Central Eureka mine in
Amador County have also produced over 100,000 pounds of lead-zinc.
The Hazel Creek mine in the East belt district of El Dorado County
is currently producing a substantial amount of by-product lead.
The precious metal deposits of Tertiary age in California are in gen-
eral restricted to the late-Tertiary volcanic areas. These deposits are
of no consequence in regard to base metals. Most of these deposits
are typical epithermal veins with free gold in highly altered volcanic
rocks in a gangue of quartz, adularia, jasper, manganese oxides, and
iron oxides. Veins that have been worked primarily for silver com-
monly contain barite in the gangue. The primary silver minerals are
generally the complex sulfo-salts. The principal mineral in the oxi-
dized zone is cerargyrite (silver chloride). It seems noteworthy that
in the Calico district, San Bernardino County, chalcopyrite, tetra-
hedrite and pyrite were found in the deepest workings below the
rich oxidized silver ore, indicating possible temperature zoning.
Environments of Deposition
Deposits of lead and zinc as well as other metallic minerals, thought
to be deposited by ascending hydrothermal solutions, are almost in-
variably found in channels or receptacles (broken rock and open
368 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
spaces) of tectonically prepared ground in the vicinity of igneous intru-
sives. Forces of unrest within the earth's crust are expressed at the
surface by long mountain chains of folded and broken strata. Such
areas are generally bounded by lines or zones of major faults caused
either by failure of the competent strata to yield entirely by plastic
deformation, resulting in reverse faults or thrusts, or by subsidence
along the flank of an uplifted area resulting in a series of normal and
antithetic faults. Igneous intrusives and volcanic invasions take the
path of least resistance along these zones of structural weakness and
move into the earth's crust.
The universal association of ore bodies with igneous intrusives is in
part structural and in part genetic. Heat and vapors from igneous
activity play a large role in mobilizing and concentrating metallic
elements. The ground is often well prepared by brecciation near in-
trusive masses, and hydrothermal solutions have easy access to zones
susceptible to replacement. The metallic ions may or may not come
directly from the cooling magmas though evidence favors this inter-
pretation in many mining camps. The important factors are that
permeable ground is available for free movement of metal-bearing
solutions. Heat and pressure from igneous sources not only supply a
motivating force for the movement of solutions but aid chemical diges-
tion, solution, and various transformations important in mobilizing,
transporting, and depositing valuable elements. Occasionally the
inherent porosity and permeability of a rock stratum is such that it
will act as a favorable aquifer and receptacle for ore-bearing solutions
with or without the assistance of tectonic deformation.
Faults. Fault zones within the earth's crust are by far the most
common receptacles of metallic ore deposits. It is here that broken and
open ground is available. Faults of importance in mineralized areas
may be broadly divided into four major groups.
(1) Low angle thrusts; generally a major feature related to diastrophic events
preceding batholithic invasion.
(2) Near vertical shear zones; may be a major feature also related to pre-intru-
sive diastrophism.
(3) Steep-dipping normal and reverse faults related to uplift and subsidence;
generally during and after igneous invasion.
(4) Low angle tension openings in blocks bounded by high angle faults; usually
contemporaneous with the normal and reverse faulting.
All four types are equally important in ore deposition. The Modoc
and Minnietta mines of the Modoc district, Inyo County, in the Basin
Ranges province occur along the sole of a large thrust on the east
flank of the Argus Range. The Carbonate and Queen of Sheba mines,
Inyo County, occur in what appears to be a thrust sheet on the east
flank of the Panamint Range. The Goodsprings district in nearby
southwestern Nevada is an excellent example of lead-zinc mineraliza-
tion within a series of overlapping thrusts (Hewett, 1931).
Thrust faults appear to have deep roots which extend to the zone
of plastic flow. They have been important channels for ore-bearing
solutions throughout the world. Thrust sheets are generally modified
by later normal and reverse faults, resulting from subsidence and ad-
justment. Aline of major thrusting extends from southeastern California
northeast through Nevada, Utah, and Wyoming. Many of these thrusts,
Nos. 3 and 4] lead and zinc in California 369
however, are barren of mineralization in the zone exposed to onr exam-
ination.
Shear zones range from major features such as the Foothill shear
zone and the San Andreas zone of faulting and shearing to minor
planes of shearing related to local features such as small intrusive
bodies. The Foothill shear zone has been deeply eroded since early
Cretaceous time and the longitudinal section exposed at the surface is
mineralized throughout its entire length. The Foothill zinc-copper de-
posits owe their origin to this structure. Many of the mines in all of
the lead-zinc districts are directly related to shear structures. Some
shear zones such as the San Andreas are not mineralized within the
zone of accessibility, however.
Normal and reverse faults are generally a smaller, much more com-
mon, feature than are thrusts. Zones of en echelon faults may, how-
ever, form major features such as the fault-block mountains of the
Basin Kanges, and the eastern scarp of the Sierra Nevada. These
structures are extremely favorable access channels for ore-bearing solu-
tions since they tend to be open and active at the time mineralizing
solutions are in motion. By this means ore-bearing solutions are often
transmitted to superficially broken, or otherwise favorable zones of
replacement at relatively shallow depths. It is not uncommon that
important ore deposits occur within these major normal and reverse
faults. The Mother Lode gold deposits are a good example. Deposits
of this type generally extend to a considerable depth. Most lead-zinc-
silver deposits in California occur, however, along minor normal and
reverse faults which are caused by superficial breakage of fault blocks
bounded by major faults. A prominent example is the Santa Rosa
mine, Inyo County. It is suggestive that pressure and temperature
gradients are too low along many major faults to allow deposition.
Horizontal to shallow-dipping tension openings within blocks
bounded by steep-dipping faults are minor structural features but are
important sites of ore deposition. Flat-lying lead-zinc-silver deposits,
known in Mexico and the southwest as "mantos" are common. They
may occur en echelon, in the vertical plane, in successive antithetic
fault blocks which are offset vertically along steep-dipping faults.
"Chimneys" of ore along the steep faults interconnect some mantos.
Tension openings may coincide with bedding planes, thus following
inherent planes of weakness. Deposits along fractures coincident to
bedding are referred to as "bedding replacements. ' ' Deposits of this
type are common at most of the lead-zinc-silver mines in the Basin
Ranges province. They are generally of greater importance than the
steeply dipping fissure vein and chimney deposits. Conspicuous exam-
ples of deposits in which mantos-type ore bodies are the most important
are the Defense mine and the Lee Flat mine, in Inyo County.
In the East Shasta district, flat-lying deposits of zinc-copper occur
along horizontal shears and tension openings between steeply dipping
faults; ore bodies occur along bedding planes between porphyritic
Balaklala rhyolite and tuffaceous beds. These openings are similar in
origin to those in the carbonate rocks of the Basin Ranges.
Folds. Folds control the movement of ore-bearing solutions and the
deposition of ore to a lesser degree than do faults. Folding is brought
about by compression which is not as conducive to the formation of
370 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
open spaces and permeable channels. Solutions under great pressure
will move through seemingly tight rocks and appear to be confined or
guided by fold structures. Minor bedding slippage, which is actually
a type of mechanical failure (faulting) probably accounts for this per-
meability. A relatively impervious bed overlying and infolded with
one of greater porosity and permeability, may act as a hood to confine
ore-bearing solutions and to restrict their upward movement. Thus
anticlinal folds are instrumental in ore control. Where anticlinal struc-
tures prevail, as at the Darwin mine, Inyo County, they are usually
flanked by major faults and are only partially responsible for ore
control. The same is true of the Shasta district where anticlinal struc-
tures are flanked by major faults. On a smaller scale, drag folds along
faults will show a "hood effect" and localize ore bodies. Such an ore
shoot, exceedingly rich but small, was found at the Surprise mine, Inyo
County.
Favorable Beds. The inherent physical and chemical properties of
certain beds may be more instrumental in ore control than are folds.
Access to favorable beds is, however, generally via major faults, unless
the strata are highly tilted and in direct contact with an intrusive body.
Lead-zinc-silver mineralization may occur over a wide horizontal or
vertical distance along very narrow beds of susceptible nature. This
is true especially in the weakly mineralized areas such as the Mineral
King area and the Camp Wishon area, Tulare County, where wide
distribution of narrow veinlets occurs. It is also true in the peripheral
regions of most major deposits of lead and zinc in the Basin Ranges
and Mojave Desert provinces. Where metallizing solutions are weakest
they are more apt to demonstrate the favorability of one bed over
another. Where replacing power is strong, all beds are replaced.
The universal association of dolomitized limestone with lead-zinc
bodies has long been noted. It has been demonstrated that dolomitized
limestone has a greater porosity than undolomitized limestone (Hewett,
1928). Silicated limestone in the vicinity of igneous contacts also
appears to be more susceptible to replacement by sulfides than nonsili-
cated limestone. Pyritized zones are definitely susceptible to replace-
ment by sulfides of lead, zinc, and copper. At many lead-zinc replace-
ment deposits, ore will favor one bed over another.
In the Shasta district all important zinc-copper deposits occur in
porphyritic rhyolite. The rhyolite made a favorable host rock for sev-
eral reasons : inherent physical properties were ideal for the formation
of horizontal tension openings between major faults; original porosity
and permeability were high ; and chemically the rhyolite was susceptible
to replacement.
In the Foothill belt most of the zinc-copper deposits occur in highly
altered meta-volcanic schists although some ore is also found in sheared
"quartz porphyry" and other rock types.
Igneous Contacts. Igneous contacts rate approximately second in
importance to faults in localizing ore deposition in the Basin Ranges
of California. This control is apparently both structural and genetic,
however indirect the genetic relationship may be. Contact zinc-lead
deposits are common throughout the Basin Ranges and Mojave Desert
provinces. At many mines lead-zinc ore grades into copper-zinc ore as
Nos. 3 and 4] lead and zinc in California 371
lead-silver decrease and copper-zinc increase in a relatively higher tem-
perature environment near intrusions. The carbonate rocks are gen-
erally silicated forming tactites of garnet, epidote, diopside, tremolite,
wollastonite, and crystalline calcite. Scheelite is also common in this
environment and a number of the early base-metal prospects are now
being prospected for tungsten.
The shape and extent of contact deposits are unpredictable and are
usually modified by combination controls of faulting, folding, and
lithology. The same factors which control the extent of the tactite zone,
such as size of the intrusive, shape of the intrusive, and attitude of
the igneous contact, also exert control over base-metal deposition.
Combination Controls. Most commonly ore deposition is controlled
by all of the foregoing factors. At Darwin, for example, ore occurs in
silicated limestone in the contact zone, as bedding replacement, in
fissure veins, and beneath folded structures. Combination controls are
the rule, not the exception, and it is usually difficult to determine what
the dominating control has been.
MINING, PROCESSING, AND UTILIZATION
Mining
The choice of mining methods to be used at a given mineral deposit
is not flexible but is dictated by size, shape, attitude, and strength of
the ore body as well as strength and general character of the wall rock.
Large scale methods such as open-pit, block-caving and sub-level caving
ire by far the cheapest mining methods but the size of California
leposits has restricted the use of such methods. The glory-hole method
:>f drawing off broken ore from below has been applied on a small scale
it some of the larger deposits, and some small-scale open cut mining
tias been feasible but, in general, more expensive underground methods
have been necessary.
Mining Methods. Mining of massive zinc-copper sulfides in the west
Shasta district where ore bodies are horizontal has, in general, pro-
3eeded from adits where topography permitted. Raises to the ore bodies
served as ore passes for stopes developed by overhand and breast stop-
ing. The horizontal stopes allowed the use of slusher-scrapers and
eliminated the need for excessive hand shoveling. Stopes developed
trom winzes were mined by underhand and breast stoping. Steep-
lipping ore bodies were developed from adits, where practical, and
)re removed by shrinkage stoping where walls were fairly strong. Min-
ng ore shoots along steep-dipping faults where ground was heavy, re-
quired square-set timbering. Some timbering was required in all the
Shasta mines.
In the East Shasta district at the Bully Hill, Rising Star, Copper
Jity, and Afterthought mines, ore shoots, in general, were steep-
lipping. This is true also of the Foothill deposits. The subdued
;opography made access by shafts and inclines necessary. Where the
;valls would stand, shrinkage stoping was generally used ; where ground
tfas heavy shrinkage stoping was not applicable and much timbering
md back-filling were necessary.

CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
Along the Mother Lode and in the East belt, veins are narrow and
steep-dipping. Mining, in general, has required access by shafts or
inclines, crosscuts to ore, and expensive sqnare-set methods of stoping.
In the Basin Ranges and Mojave Desert where carbonate rocks pre-
dominate, walls stand well and require little timbering. Large open-
stopes are common, and it is seldom necessary to leave pillars. Mining
costs are lower than in the other districts. Shrinkage stoping is usually
possible in the steep-dipping ore shoots and ore from large open stopes
can be cheaply removed by mechanical equipment. Where topography
permits, raises from haulage adits develop the shallow levels. Deeper
levels are generally developed from underground shafts via crosscuts.
Most small mines throughout California have been developed by
irregular workings because of the necessity to stick close to ore in
order to make mining pay as it proceeded. As a result of this unor-
ganized development, low grade ore was left in inaccessible workings.
This is true especially where ground is heavy and will not stand without
timbering. Abandoned workings soon cave and flood, and because of
the lack of mine records and maps, reopening of a deposit for milling-
grade ore is usually considered too much of a risk. Diamond drilling
of known mineralized districts is usually the best approach to further
exploration.
In the desert regions mine openings remain accessible for much
longer periods, even where no timbering has been used. Because of this,
intermittent operation has been possible. Usually, no great expense is
involved in reopening a mine for further exploratory work. Neverthe-
less, developments have, in large, been confined to shipping-grade ores,
and most mine workings followed ore showings. The net result is a
very irregular pattern of mine workings with much unexplored ground
in the immediate vicinity of known mineralization. It remains for

LEAD AND ZINC IN CALIFORNIA

374 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
organized companies to systematically explore and develop these
deposits. The small mine operator usually cannot afford the expense
and risk of extensive or intensive underground development.
The economics of mining is no simple matter and many factors in-
fluence the decision as to what mining methods are to be employed.
The complex zinc-copper ores of the Shasta and Foothill districts must
be milled and concentrated to produce a marketable product. If ore is
left too long in the stopes, superficial oxidation of the sulfides adds to
the difficulty of successfully separating the minerals by flotation. This
one reason may be a strong argument against such methods as shrink-
age stoping which involves leaving the ore in the stopes for long periods.
More than anything else, the small operator has to make regular ship-
ments and elaborate preparations to mine ore must be avoided. By
necessity the small operator has practiced a system of "high-grading"
which has become known as " chloriding. " The expression originated
in the silver camps where the high grade ore was in the form of silver
chloride in the oxidized zone, and the high grade chloride was selectively
mined.
The scarcity of water for milling purposes in the desert regions has
had a great influence on the development of lead-zinc-silver mining
practice. This factor coupled with the smallness of deposits has led
to the practice of high-grading to meet shipping requirements. At
many of the small mines, selective blasting and hand-sorting is still
practiced. Much milling grade ore never reaches the dump, but is left
in backfilled stopes and "dry walls"; only the high grade is hoisted or
trammed out.
Shipping Grade Ores. Only rarely will complex zinc-copper ores
bear shipping directly to the smelter without benefication. Because of
the deleterious effect of zinc to the process of copper smelting, it is
heavily penalized and a negative return is realized by the shipper. Only
when copper is high enough to bear the freight, pay for the base
smelting charge, pay the penalty for zinc, and still bring a profitable
return can these ores be shipped directly. During the early copper-
mining period when secondarily enriched ores were mined from the
oxidized zone, ore was shipped to Swansea, Wales. Ores of this grade
are not known in California today. From 2 to 5 percent copper is
considered good ore in the primary zone, and zinc is nearly always
present in amounts averaging from 7 to 12 percent. This ore is only
economical when milled, and separate zinc and copper concentrates
made.
Copper and lead do not seriously interfere with each other during
the smelting process and for this reason complex ores in which lead
predominates over zinc have been profitable to ship directly. It is gen-
erally the gold-silver content that makes these ores profitable, however.
Where scheelite is present in economic concentrations the ores are now
milled to make a separate scheelite concentrate and the copper, lead,
and precious metals are recovered in a base-metal concentrate as a
by-product.
Gold and silver ores that contain lead may be shipped directly to
a precious metal or lead smelter. This is done where gold-silver value
is high and not amenable to recovery by amalgamation or cyanidation.
tfos. 3 and 4] lead and zinc in California 375
kVhen the gold or silver is finely divided in a silicious gangue or locked
n sulfides, it is often more economical to ship directly than to mill,
^ery finely divided particles are not amenable to amalgamation and
'urthermore excessive grinding is required to free the particles for
•ecovery by either amalgamation or cyanidatiou. Often minerals with
l deleterious effect to the cyanide solution will make this form of treat-
nent impracticable. Shipping may be the only alternative.
The lead-zinc-silver ores of southeastern California form the bulk
if shipping grade ores. If lead is high and zinc negligible, the ore is
hipped to a lead smelter ; the zinc is penalized. If zinc is an important
onstituent the ore is either shipped to a zinc smelter or combined metal
melter. Where lead forms 20 percent or more of the ore it is generally
nore economical to ship directly to a smelter than to mill. Shipping
>rade zinc ore should contain 40 percent or more zinc. Silver and gold
ontent may determine whether or not an ore can be shipped profitably.
Is the precious metal content rises, the percentage of base-metal re-
hired to meet shipping grade drops.
Many considerations influence the disposition of ore in the ultimate
neans of marketing. Moderate to low grade ores that will bear ship-
)ing can usually be milled to show a greater profit. Shipping costs are
l very large item and not only is a concentrate less bulky to ship but
•eceives a premium for high metal content at the smelter; separate
:oncentrates are shipped and zinc is paid for also. Each operation has
ts individual problems, and it must be determined whether or not mill-
ng expenses will be more than compensated for by freight savings and
>onus payments. Usually the limiting factor is the proven reserve of
»re, or the fact that the ore is not amenable to treatment by milling.
^. small mine cannot support a large mill, and a small mill costs more
per ton of capacity) to build and operate. Even if a deposit is large,
he scarcity of water may prohibit milling.
The problem of what can be shipped at a profit and to which smelter
t should be shipped is critical. Smelting is a competitive business and
'open schedules" are not always closely adhered to. Though the small
hipper has little bargaining power, if he is a regular shipper he can
isually make special arrangement with a smelter which will give him
better net return than indicated by the smelter's "open schedule."
["he larger and more regular shipper has correspondingly more bargain-
ng power. By special arrangement with the smelter, even mine dump
material has been shipped at a profit. Such cases arise when a smelter
Leeds a certain type of ore to add to the furnace charge in order to
orm the proper slag. A lead or precious metal smelter rarely finds a
Leed to solicit siliceous material but generally pays a premium on
ron and lime. If a large operation is contemplated, trial shipments are
Lsually sent to smelters, to custom mills, and to physical laboratories
or data on proper milling procedure. In large operations a pilot-plant
often built in advance of the mill. A small prospective producer is
imited and usually ships trial lots to smelters and to custom mills.

Milling of Complex Ores.2 The technology relating to mineral dress-

erties of minerals and aims at concentrating and separating the valuable
mineral constituents from each other as well as from the worthless, or
gangue minerals. The process involves sizing and conditioning of ore
particles, grinding to effect mechanical separation, and concentration
and separation of the valuable minerals. Concentration in mineral
dressing may be accomplished by various means including gravity
separation, flotation, magnetic separation, or separation by size differ-
ential. All steps depend on the physical properties of minerals and
thus are classified as mechanical processes. Each ore presents a special
problem and the mill man will take advantage of each of the physical
properties of the minerals involved.
Sizing of ore particles begins in the stopes where ore is reduced to
a size convenient for transport to the mill. Grizzlies are employed
underground and again at the crude-ore bins. Crude ores ordinarily
begin their journey through the mill at a primary jaw-crusher or cone-
crusher which reduce ore to the general size of 3 or 4 inches. Secondary
crushers of similar type reduce these particles to about a quarter of an
inch. The next step is fine grinding to about 60 mesh or smaller. This
is generally accomplished by wet-grinding in a ball or rod mill. Over-
flow from the ball or rod mill passes to a classifier of cone, screw, or
rake type where particles are separated by the process of hydraulic
settling. As heavier (larger) particles settle they are dragged along
the bottom of the classifier by a turning screw or raking action. These
particles are returned for further grinding and the overflow from the
classifier which contains the fine particles, passes to the separation and
concentration section of the mill.
Bulk concentrates containing a mixture of the valuable metals are
sometimes produced, especially if one valuable constituent predom-
inates over all others and a marketable concentrate can be produced.
Bulk concentration may be accomplished by gravity separation in pul-
sating jigs or on vibrating tables, or by bulk flotation whereby the
sulfides are activated and gangue minerals depressed. Magnetic con-
stituents are sometimes removed by magnetic separators. Where it is
desirable to separate two or more valuable minerals to form individual
concentrates, selective flotation is usually most applicable. Gravity dif-
ferential is usually not sufficient to allow a complete separation by
jigging or tabling. A bulk concentrate not amenable to selective flota-
tion may be further concentrated by the Waetz process (see section on
smelting). Separate zinc oxide and lead oxide products can be pro-
duced; also a sinter containing the copper and precious metals.
The discovery that mineral surfaces could be conditioned in such
a way that they would resist wetting and could be floated, lead to the
development of the flotation process. Conditioning is accomplished by
adding minute quantities of certain organic substances known as col-
lectors to an aqueous suspension of fine mineral particles. The organic
molecule attaches itself to the sulfide particle and renders it unwet-
table. The mineral pulp is then agitated in a flotation cell and air
bubbles introduced at the bottom of the cell will collect the conditioned
sulfide particles and carry them to the surface. To prevent the bubbles
from breaking and losing their burden at the surface, frothers are
added to give strength to the bubbles. The froth is floated or raked off
continuously at the top of the cell. The gangue minerals are not affected

)y the conditioners or collectors and will remain wetted and in sus-
pension.
Each mineral has a different magnitude of wettability and by the
Droper choice of reagents one sulfide can be activated while all others
ire depressed. A sulfide that is easily floated may be separated from
i less floatable sulfide just by adding a minimum of the collecting agent.
Various oragnic compounds have different affinities for different sul-
ides and it is possible to selectively float one sulfide at a time.
Common collectors are amyl xanthate and ethyl xanthate. The most
jommon frothing agents are pine oil and cresylic acid. The relative
ilkalinity or acidity (pH) is important in selective flotation and other
-egulating reagents known as modifiers or controllers are added to the
Dulp to insure the desired pH. Common acids and bases are used for
;his purpose. Other modifiers and controllers include inorganic salts
mch as copper sulfate and sodium cyanide, complex organic salts which
ict as detergents against deleterious coatings on mineral particles, and
substances which exhibit collodial properties such as starch.
By controlling the activation of minerals through selection of acti-
vating reagents, depressing reagents, and modifiers the mineral con-
stituents may be floated separately. The pulp is conditioned to activate
;he first mineral to be separated. The first "rougher cell" will float
;he bulk of the activated mineral and subsequent cells in the series will
;reat the middling product which did not float in the first cell. The
ast rougher cell will contain the tailings and the depressed ore min-
erals to be activated and separated later. Froth from the rougher cells
s further cleaned in a series of ' ' cleaner cells. ' ' The concentrate from
;his series goes to a thickener and dryer and then to a concentrate bin
ready for shipment. The tailings from the cleaner cells are usually
returned to the first rougher cell since they still contain value. The
;ailings from the series of rougher cells passes through a second recon-
litioning process where the next mineral to be activated and floated
s conditioned with the appropriate collectors and modifiers. The process
)f "roughing" and "cleaning" is repeated in a second bank of cells,
rhe tailings from the second set of rougher cells may pass through a
:hird cycle if another mineral is worthy of recovery.
Milling of Zinc-Copper Ores. The milling of zinc-copper ores pre-
sents one of the most difficult problems in mineral dressing. In these
)res, the intimate association of sphalerite and the copper sulfides
makes mechanical separation difficult. The fine grinding which is re-
quired to separate the minerals, besides being expensive, produces a
slime which is difficult to handle. In attempting to liberate all particles,
those which were reduced to a small size early in the grinding circuit
suffer unnecessary grinding. In order to produce a marketable product
which will bring a high return, zinc must be^kept low in copper con-
centrates, and zinc concentrates below a certain grade are penalized at
the zinc smelter. To realize a fair return on lead contained, it must be
shipped to a lead smelter. Lead contained in copper concentrates is
usually paid for at low rates. Therefore it is usually desirable to pro-
duce separate concentrates.
In the usual scheme of selective flotation of zinc-copper ores, pyrite
ind sphalerite are depressed by conditioning of the pulp with cyanide
and zinc sulfate; the copper minerals are floated with a xanthate col-
2—57110
378 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
lector in a neutral environment. The copper concentrate goes to
"cleaner cells" and the tailings are reconditioned with copper sulfate
which forms a coating and renders the sphalerite floatable. Lime is
added to the pulp to raise the pH and suppress the pyrite. Sodium
aerofloat is a common collector used to float the sphalerite. A special
frothing agent is also used. Minor amounts of galena in these ores gen-
erally are not important and usually appear in the copper concentrate.
One of the great difficulties in milling zinc-copper ores is the tend-
ency for sphalerite to become coated with copper sulfide. This tendency
is strongest in high pyrite ores where oxidation of the pyrite forms
sulfurous acid which dissolves copper and redeposits it on sphalerite
surfaces. This action pre-activates sphalerite and makes it hard to
depress in the copper circuit. Superficial oxidation of ore in the stopes
must be avoided. This makes it impraticable at times to use methods
such as shrinkage stoping. Ore must be rushed to the mill as soon as
possible. This further causes the annoyance of surges in grade since
ore cannot be held for blending. Precautions are usually taken to pre-
vent pre-activation of sphalerite in the grinding circut, by keeping
the pH high with lime or soda ash.
With modern milling practice about 95 percent of the contained zinc
and 85 percent of the contained copper can be recovered in a bulk
flotation concentrate. Recovery in separate concentrates is lower. Zinc
concentrates will contain a few percent copper and copper concentrates
will contain some zinc.
"When complex ores are milled, especially those mined primarily for
their precious metal content, or in some cases for their tungsten con-
tent, a bulk base-metal concentrate may be more feasible, particularly
if it is strictly a by-product, as in tungsten milling.
Milling of Lead-Zinc-Silver Ores. The milling of lead-zinc-silver
ores presents special problems and oxidized ores must be handled sep-
arately. If the oxidized lead ore has been well leached of its zinc con-
tent and contains about 20 percent or more lead, it is generally more
economical to ship directly to a lead smelter than to mill. If the oxi-
dized ore does not meet shipping requirements it must be segregated
in the stopes and handled separately from the sulfide ore. This is true
because cerussite (lead carbonate), anglesite (lead sulfate), and galena
with oxidized coatings, cannot be activated in the sulfide circuits but
must be treated with sodium sulfide previous to flotation. Sodium sul-
fide forms a thin lead sulfide coating on the carbonate and sulfate
minerals making them respond like galena in the flotation circuit. By
this means a good recovery can be obtained. The primary sulfide ore is
treated in a separate circuit where selective flotation of sphalerite and
galena are conducted in a manner similar to the selective flotation of
complex zinc-copper ores.
The lead concentrate generally contains most of the minor copper
which is present, and a large proportion of the gold and silver, as well
as a few percent zinc. Zinc concentrates unavoidably contain some lead,
part of the silver, and minor gold, and copper, as well as cadmium.
Zinc concentrates in California contain from 0.22 to 0.28 percent cad-
mium in all districts. This is eventually recovered from flue dust at
lead smelters and from fume and dust at zinc smelters.
Nos. 3 and 4] lead and zinc in California 379
SMELTING AND REFINING3
The purpose of smelting is to reduce chemical compounds such as
sulfides to the metallic state or to a mixture of metals and gangue ma-
terial higher in metal content, thereby eliminating most of the worth-
less material. Two processes are in use ; pyrometallurgy whereby fusion
converts the furnace charge into a molten state which allows settling
of the metals by gravity, and distillation whereby the metal content is
distilled off with or without complete fusion of the charge. Pyrometal-
lurgical methods are used in the smelting of copper and lead. Zinc,
because of its low boiling point, is amenable to the distillation process.
Lead Smelting. The pyrometallurgical smelting of lead is conducted
in a low, rectangular blast furnace. Air is blown in from the sides near
the bottom, and the charge is mechanically fed in from the top which
is about 20 feet above the tapping spout. The charge contains about
75 percent sintered concentrates and ore, about 12 percent coke, and
the remainder is fluxing material. Sintered ore and concentrates are
blended in such a way as to form a charge with the correct propor-
tions of the principal fluxing materials (lime, silica, and iron). This
eliminates the need for adding undue amounts of fluxing materials con-
taining no metal values. The coke contained in the charge supplies the
fuel and acts as a reducing agent in combination with the air being
blown through the charge. In this reducing atmosphere metallic lead
forms and flows to the bottom of the charge where it is siphoned or
tapped off and sent to the refinery. The fluxing materials form a liquid
slag which floats above the molten lead.
Zinc contained in the lead ores and concentrates goes into the slag
and into the flue dust. Slags contain from 5 to 12 percent zinc and may
be fumed, for their zinc content. The flue dust which contains zinc,
3opper, cadmium, lead, and minor silver and gold is recovered in a
baghouse and subsequently smelted or otherwise treated. Flue dust may
be blended with ores and concentrates and returned to the blast fur-
nace. Most of the precious metals are contained in the lead melt and
are later recovered at the refinery. Copper contained in the charge
forms copper-iron speiss which is skimmed off in a drossing kettle and
subsequently treated to recover the copper.
Zinc Smelting and Fuming. The smelting of zinc is more involved
than the smelting of copper or lead, and recovery is generally lower,
rhese facts account for the lower return to the miner. The physical
3hemistry of zinc, and especially its low boiling point (905° C.) restrict
smelting procedures and make recovery expensive and involved. Sev-
eral processes are in use.
The batch retort process which is one of the older methods, employs
the use of small (7 inches by 4 to 6 feet) cylindrical retorts of refrac-
tory material, which stand vertically in a gas-fired furnace. Condensers
ire attached to the open ends. The ore and reducing agent is added in
matches every 24 hours. Spelter or impure zinc may be tapped several
:imes between successive charges.

386 CALIFORNIA JOURNAL OF MINES AND GEOLOGY [Vol. 53
The New Jersey Zinc Company has developed a continuous vertical
retort process (Bunce and Handwerk, 1936) which is much more
efficient and has larger capacity.
In the electrothermic process (Weaton, 1936) used by St. Joseph
Lead Company, sintered ore and coke are mixed in equal proportions
to form an electrically conductive charge. Current passing through the
charge supplies sufficient heat for distillation. Fumes are pumped by
vacuum and forced to bubble through a bath of molten zinc. With
careful temperature control of the zinc bath, fractional distillation pro-
duces a high quality zinc 99.97 percent pure.
The Waelz process (Harris, 1936) is principally one of concentra-
tion since a finished product is not produced. The process involves
calcining in a rotary kiln. The fume produced is an impure zinc oxide
containing lead, cadmium, and other impurities.
The electrolytic process (Laist and Caples, 1945) is divided into
three steps. First, ore and concentrates are roasted and the zinc sulfide
is converted to zinc oxide and zinc sulfate. The calcines are then leached
with sulfuric acid producing a zinc sulfate solution which after purifi-
cation goes to electrolytic cells where pure zinc is deposited elec-
trolytically.
Copper Smelting. Copper ores and concentrates are usually roasted
prior to smelting. This eliminates most of the sulfur and forms a
product more uniform in size and composition both of which aid in
better control of the smelting process. Fluxing material is added to
the sinter-cake and the loose mixture is charged in a refractory lined
vessel about 130 feet long, 30 feet wide, and 3 feet deep. The hearth
is covered by a low refractory-lined arch to confine the heat. Where
possible, much of the fluxing material is in the form of low grade
copper, gold, or silver ore. Gas, oil, or coal dust are burned above the
charge. During fusion the fluxing materials combine with the gangue
minerals to form a siliceous slag which will rise to the top while metallic
copper, some of the iron and sulfur will form a heavy matte in the
bottom of the vessel. If the charge is proper and contains the right
proportions of fluxing material (lime and silica) the slag should be
free of copper and form a fluid lime-iron silica melt which can be
tapped off near the top of the vessel. Copper matte containing the
precious metals is tapped near the bottom. This is known as a reverber-
atory furnace.
The liquid matte is delivered to the converter which is a refractory-
lined vessel equipped with air inlets called tuyeres. Air is blown
through the molten matte to remove the excess sulfur. This produces
a rich copper-sulfur mixture called white metal. A second stage of
blowing further removes sulfur and produces impure or blister copper
which is sent to the refinery.
Zinc contained in the copper concentrates causes much trouble in
the charge of the reverberatory furnaces and for this reason is heavily
penalized in copper ore or concentrates.
Smelting of Siliceous Gold-Silver Ores. Most of the gold and silver
produced from siliceous ores is recovered at the mine by amalgamation
or cyanidation. When the precious metals are locked in base-metal
sulfides or the ore is not generally amenable to direct recovery methods,
Nos. 3 and 4] lead and zinc in California 387
concentrates are shipped to smelters. Such concentrates usually do not
contain more than a few percent of the base metals. They are known
as dry ores and are used at the lead smelter to flux lead ores and con-
centrates. For this reason all insolubles contained are usually allowed
free of penalties. It is very seldom that lead smelters are obliged to
solicit siliceous ores, however, and for this reason premiums are almost
never paid.
The precious metals have a natural affinity for lead and are recov-
ered from the lead during refining. Recovery is high.
Refining of Lead. Molten lead from the blast furnace contains minor
impurities of arsenic, bismuth, antimony, copper and tin, and most of
the silver and gold. The first step in refining is the transfer of the
metal to large drossing kettles where it is agitated with air to oxidize
part of the impurities. Copper-lead arsenides and antimonides float to
the surface and are skimmed off. This dross is further treated to recover
the copper and lead. The next step is to ' ' soften ' ' the lead by removing
the antimony and tin as oxides which are skimmed off in the ' ' softening
kettle." After softening, the lead goes to the de-silvering kettles where
metallic zinc is added. Gold and silver combine with the zinc to form
a lightweight dross which floats on the lead. This material is skimmed
off and sent to the silver refinery. The lead is then treated to remove
the bismuth, and finally poured into lead pigs.
The zinc-lead dross which contains the gold and silver is distilled to
drive off the zinc. The remaining lead contains all of the gold-silver
and is treated in cupelling furnaces to remove the lead as an oxide. The
remaining gold-silver bullion is cast into anodes which are then placed
in electrolytic cells to separate the gold and silver. Silver crystals form
on the cathodes, are collected, melted down, and cast into bars. The gold
accumulates as a black sludge in the bottom of the electrolytic cell. This
sludge is treated with sulfuric acid and refined gold is produced by the
Wohlwill process.
Refining Zinc. The zinc produced by the electrolytic process needs
no further refining and zinc recovered as zinc oxide fume is marketable
as such. Zinc produced by distillation methods contains some lead and
cadmium impurities. If a high purity zinc is desired it may be obtained
either by the electrolytic process or by the reflux fractional distilla-
tion process. (Ingalls, 1945). Molten spelter from the retort process
is revaporized and forced up through a chamber where it comes in
contact with falling droplets of molten lead. Lead is thus removed and
the rising vapor becomes richer in zinc and cadmium. A second cham-
ber with falling zinc droplets removes the zinc from the fume and
cadmium passes up and out as a vapor and dust. By this method zinc
99.99 percent pure can be made.
Utilization
Lead and zinc are two of the most common base metals upon which
industry relies for a wide variety of fabricated commodities. Their
production and consumption are exceeded only by steel, copper, and
aluminum.
Lead is firmly entrenched in most of its uses but is not entirely free
of competition from substitutes. The physical and chemical properties

which make lead of great value in industry are its softness, or easy
workability, its weight, high resistance to corrosion, high boiling point
and low melting point, alloy ability with other metals, and its shielding
effect to radiation. The relative cheapness of lead in comparison to other
base metals is, of course, a prime factor.
The physical and chemical properties that give value to zinc in
modern industry are primarily its resistance to corrosion and its alloy-
ability with other metals. Here again the relative cheapness of zinc
accounts for its wide use and the threat of substitutes is much more
formidable than for lead.
The relative magnitude of uses of lead and zinc are clearly demon-
strated by the accompanying tables and have not varied greatly over
the past 20 years. The automotive industry consumes over 40 percent
of the total lead in the form of storage batteries and tetraethyl lead.
Most of the lead used in storage batteries is ultimately recovered as
scrap. The major losses are in lead consumed in tetraethyl lead and in
pigments.
Aluminum and plastics are now in competition with lead in certain
types of cable sheathing; however, the greater expense of aluminum
prevents any serious competition at present. Nickel-cadmium storage
batteries though of much greater initial cost, have greater life and
efficiency. They are not generally available to the public at present but
may in the future be a serious threat to lead in its primary field of
use. Titanium and other pigments are being used more and more in
place of lead pigments, and the use of lead foil has declined in favor
of plastics and aluminum. The only new use which may be of sig-
nificance to the future of lead is its use as a shield in atomic radiation
devices.
The value of zinc in the galvanizing and zinc alloy industries has
resulted from the relative abundance and cheapness of this common
base metal. Zinc galvanized steel has filled an immediate need for
cheap, corrosion resistant material. The main disadvantage is the
weight and, for this reason, aluminum sheeting, though of higher cost,
has become a serious competitor. As the cost of aluminum has been
reduced through technological advances in smelting, aluminum has also
become competitive in the die-casting industry. The reluctance of manu-
facturers to switch to substitutes has had a moderating effect on the
relative decline of the zinc industry. The price of zinc must remain
considerably below aluminum in order to prevent a great loss to this
formidable competitor.
The accompanying price chart shows the price fluctuation from which
the relative demand can be inferred. The relative stability of lead over
zinc is probably due in large part to its great recoverability ; sudden
demand is more readily supplied from available scrap.
